Nga Tikanga Maimoatanga mo te Whakakikorua i te Hau Whakamuku Cyanide

Kupu Whakataki

I roto i te umanga whakakikorua hiko , e whakamahia whānuitia ana ngā cyanide hei tāpiringa whakakikorua hiko nui. Ka taea e rātou te whakapai ake i te kounga me te whai huatanga o ngā paparanga whakakikorua hiko. Heoi, i roto i te tukanga whakakikorua hiko, ka puta he hau putanga kei roto he cyanide , kei roto ngā matū tino paitini pēnei i te hauwai cyanide (HCN). He tūraru nui tēnei ki te taiao me te hauora o te tangata. Nō reira, he mea nui te maimoatanga whai hua o te hau putanga cyanide whakakikorua hiko.

Ko nga Puna o te Hiko Whakakikorua i te Hau Whakamutunga Cyanide

1. Ngā Tāke Whakakikorua Hiko : I te wā e whakakikoruatia ana, nā te mimiti haere o te irahiko me te hau i puta mai i te tauhohenga hiko, ka tukuna te hau putanga kei roto he cyanide. Hei tauira, i te whakakikoruatia o te koura me te hiriwa ki te cyanide, ka mimiti haere ngā matū cyanide i roto i te otinga whakakikorua i raro i te mahi a te wera me te iahiko hiko.

2. Ngā Tukanga Horoi : Whai muri i te whakakikoruatanga hiko, ina horoia ngā wahi mahi ki ngā wai horoi kei roto ngā Cyanide , ka memeha haere te iti o ngā cyanide. Ahakoa he iti te kukū o ngā cyanide i roto i te wai horoi, ka raru tonu te parahanga mēnā ka kohia, ka memeha haere hoki mō te wā roa.

3. Te Maimoatanga o ngā Wai Para : Mena he hē te maimoatanga wai para i runga i te whakakikorua hiko, ka puta pea te hau cyanide. I roto i te tukanga maimoatanga o ngā wai para kei roto te cyanide, ki te kore e pai te whakahaere i ngā āhuatanga tauhohenga, ka puta pea te hau HCN i te pirau o ngā cyanide ka uru ki te āhuarangi.

4. Ngā Taputapu Āwhina : Tērā pea ka puta he iti noa iho o te hau putanga i ngā taputapu pēnei i ngā pūnaha hauhautanga me ngā taputapu whakamahana i te wā e whakamahia ana. Ahakoa he iti te nui, i te mea he nui te paitini o ngā cyanide, kāore e taea te wareware.

Ko nga ahuatanga o te Hiko Whakakikorua i te Hau Whakamutunga Cyanide

1. Te Paitini Nui : He tino paitini ngā matū cyanide, inā koa ko te HCN. Ahakoa he iti rawa te kukū, ka taea e rātou te whakararu i te tinana tangata. Mā te hongi i te hau putanga kei roto he cyanide ka puta ngā tohu pēnei i te ānini, te whanoke, te poto o te manawa, ā, i ngā wā kino rawa atu, ka taea te whakararu i te ora.

2. He iti te kukū engari he pānga tāpiripiri : I te nuinga o te wā, he iti noa te kukū o te hau putanga cyanide whakakikoruatia hiko, engari nā te whakaputanga tonu i te wā o te tukanga whakakikoruatia hiko, ki te kore e tukatukahia pai, ka pā te pānga tāpiripiri ki te taiao mō te wā roa.

Tukatuka Maimoatanga o te Whakakikorua i te Hau Whakamuku Cyanide

1. Kohinga Puawai Putea

• Whakanohoia nga putunga kohinga hau, etahi atu taputapu kohinga ranei ki nga waahi whakangao hau. Ko enei taputapu kohikohi me hangaia kia rite ki te tukanga whakaputa me te whakatakotoranga motuhake kia pai ai te kohia o te hau. Hei tauira, i roto i tetahi awheawhe whakakikorua hiko nui, ka taea te whakamahi i te huinga o nga kohinga kohinga a-rohe me nga punaha whakangao hau ki te hopu matawhānui i te hau rewharewha kei roto cyanide.

2. Whakamaatua

• Te Tango Puehu : Whakamahia ngā taputapu tango puehu pēnei i ngā tātari putea, ngā taputapu whakapūmau hiko rānei hei tango i ngā matūriki i roto i te hau putanga. Tērā pea kei roto i ngā matūriki ngā matūriki i runga i tōna mata, ā, mā te tango i mua i aua mea ka pai ake te whai huatanga o te maimoatanga i muri mai, ā, ka ārai i te kino o ngā taputapu maimoatanga.

• Te Whakakore Huka me te Tango Makuku : I te mea kei roto pea i te hau putanga te kohu wai me te kohu hinu, whakamahia ngā taputapu tango kohu me ngā mea whakamaroke hau hei tango i ēnei matū. Ka pā te kohu wai ki te whai huatanga o te tauhohenga o ngā tukanga maimoatanga i muri mai, ā, ka pā pea te kohu hinu ki te mahi a ngā whakakorikori me ngā mea mimiti.

3. Tukanga Maimoatanga Matua

• Tikanga Korohanga Matū

• Mātāpono : Whakamahia ngā otinga kawakore pērā i te hauwai konutai (NaOH) te hauwai konupūmā rānei (Ca(OH)₂) hei mimiti. Ka tauhohe te cyanide i roto i te hau putanga ki te otinga kawakore hei hanga tote cyanide. Hei tauira, ka tauhohe te HCN ki te NaOH hei hanga Konutai Cyanide (NaCN), ka taea te tango pai i te cyanide mai i te hau putanga.

• Tukanga : Ka tomo te hau putanga ki te pourewa mimiti matū, ka pa atu ki te otinga kawakore i rehuhia i roto i te āhua au-whakamuri. Ko te tikanga ka whakakīia te pourewa mimiti ki ngā rauemi tākai hei whakanui ake i te horahanga pa i waenga i te hau me te wai, hei whakapai ake i te whai huatanga o te mimiti.

• Tikanga Okihanga Catalytic

• Mātāpono : I raro i te mahi a te whakakorikori, ka waikurahia te cyanide i roto i te hau putanga ki te hauhā waro kore-paitini (CO₂), te wai (H₂O), me te hauota (N₂). Ko ngā whakakorikori noa ko ngā whakakorikori konganuku utu nui (pērā i te platinum, te palladium) me ngā whakakorikori waikura konganuku (pērā i te titanium dioxide, te vanadium pentoxide).

• Tukanga : Whai muri i te haere i roto i te pourewa mimiti matū, ka tomo te hau putanga ki te taputapu whakapūngao matū. Kei te taputapu he moenga whakapūngao matū, ā, ka haere te hau putanga mā roto i te moenga whakapūngao matū i tētahi pāmahana me te tere o te wāhi. Ka whakatairangahia e te whakapūngao matū te tauhohenga whakapūngao matū o te cyanide, ka whakaitihia tōna paitini.

• Tikanga Makuku Makuku

• Mātāpono : Whakamahia he pourewa mimiti mākū hei rehu i tētahi wai mimiti hei mimiti i te cyanide i roto i te hau putanga. Ka taea te whakamahi i te wai mimiti hei waihanga matū motuhake i hangaia kia rite ki ngā āhuatanga o te cyanide.

• Tukanga : Ka tomo te hau putanga ki te pourewa mimiti mākū mai i raro, ā, ka rehuhia te mea mimiti mai i runga. Kei te pā atu ngā mea e rua i roto i te pourewa, ā, ka mimitihia te cyanide i roto i te hau putanga e te mea mimiti. Kātahi ka tukatukahia motuhaketia te wai mimiti hei tango i te cyanide.

• Tikanga Maimoatanga Koiora

• Mātāpono : Kei ētahi moroiti te kaha ki te wawahi i te cyanide. Whakamahia ēnei moroiti hei wawahi i te cyanide i roto i te hau putanga i roto i te taiao e tika ana.

• Tukanga : Ka whakamakukuhia te hau putanga i te tuatahi, kātahi ka uru ki te taputapu maimoatanga koiora. Kei roto i te taputapu he kawe kiriata koiora e piri ana ngā moroiti ki runga. Ka mimitihia te cyanide i roto i te hau putanga e te kiriata koiora, ā, ka pirauhia e ngā moroiti hei matū kore-paitini. Heoi, me tino whakahaere tēnei tikanga i ngā āhuatanga taiao pēnei i te pāmahana, te pH, me te whakarato matūkai kia pai ai te tipu me te mahi a ngā moroiti.

4. Te Aroturuki me te Tukunga

• Whakauruhia nga taputapu tirotiro ipurangi ki te tauranga tuku hau remu kia mau tonu te aro turuki i te kukū o te cyanide me etahi atu parakino kei roto i te hau remu. Ka tutuki noa te hau remu ki nga paerewa tukunga o te motu me te rohe ka tukuna ki te hau. Me tuhi nga raraunga aro turuki me te tuku korero i ia wa hei whakarite i nga hanganga ture.

mātai take

He raru nui ki tetahi hinonga whakakikorua hiko ki te parahanga hau maru o te cyanide i roto i te mahi whakaputa. Hei whakatau i tenei raru, i whakamahia e te umanga nga tikanga maimoatanga e whai ake nei:

1. Te Kohikohi Hau Putanga : I tāutahia he taupoki kohikohi hau tino whai hua ki runga ake i te tāke whakakikorua hiko hei whakarite kia neke atu i te 95% o te hau putanga kua kohia.

2. Te Maimoatanga o mua : Whakatūria he pūnaha tango puehu me te whakamaroke hei tango tika i ngā matūriki me te mamaoa wai i roto i te hau putanga.

3. Te Maimoatanga Matua : I whakamahia te whakakotahitanga o ngā tukanga mimiti matū me te waikura whakaterenga. Tuatahi, ka tomo te hau putanga ki te pourewa mimiti matū kua whakakiia ki te otinga NaOH hei tango i te nuinga o te cyanide. Kātahi ka waikurahia anō te cyanide e toe ana, ā, ka pirau i roto i te taputapu waikura whakaterenga.

4. Aroturuki : I tāutahia he pūnaha aroturuki ipurangi hei whakarite kia tutuki i te hau putanga kua tukatukahia ngā paerewa tukunga ā-motu.

I muri i te whakatinanatanga o enei tikanga, ka tino heke te kukū o te cyanide i roto i te hau whakapau o te hinonga, he pai te whakaiti i te parahanga o te taiao me te tiaki i te hauora o nga kaimahi.

Opaniraa

Ko te maimoatanga o te hau ngongo cyanide electroplating he tikanga nui hei tiaki i te taiao me te hauora o te tangata i roto i te umanga hiko. Ma te tango i nga kohinga hau rewharewha e tika ana, te maimoatanga o mua, te maimoatanga matua, me te aro turuki me te tuku i nga tikanga, ka taea te whakaiti i te kukū o te cyanide i roto i te hau rewharewha ki te whakatutuki i nga whakaritenga o te tiaki taiao. I nga wa kei te heke mai, me te whakapai tonu o nga whakaritenga tiaki taiao, me arotau tonu nga hinonga whakakikorua hiko me te whakahou i nga tikanga maimoatanga hau pau ki te whakatutuki i te whanaketanga taumau.
