Ndedzipi nzira dzakajairika dzekurapa cyanide - ine tsvina yemvura?

Mumamiriro ezvinhu aripo ekuenderera mberi nekuvandudza mazinga ekutonga kwezvakatipoteredza uye kuwedzera kuomesera zvinodiwa, akawanda minda anoshandisa cyanides gadzira huwandu hwakawanda hwemvura inokuvadza inorasa. Kana ikasashandiswa nemazvo, inogona kuisa njodzi kuhutano hwevanhu. Kuzadzisa zvinangwa zviviri zvekusarasa uye kusakuvadza, Nzira dzekugadzirisa zvakare inogona kugamuchirwa kugadzirisa nyaya iyi.

Acidification Method

Nheyo huru yeiyi nzira ndeyekuwedzera sulfuric acid kune cyanide - ine tsvina yemvura yakadai Sodium cyanide mvura yetsvina uye gadzirisa pH kusvika ku1.5. Izvi zvinoshandura CN - kuita HCN. Sezvo nzvimbo yekubikira yeHCN yakadzikira zvakanyanya, 26.5 ℃ chete, inogona kupukunyuka kubva mugadziriso patembiricha yekamuri. Iyo yakapukunyuka HCN gasi inopinzwa mumudziyo uye inotorwa nealkaline solution (sodium hydroxide kana calcium hydroxide solution). Somugumisiro, 20% - 30% cyanide solution inowanikwa, inogona kushandiswa zvakare.

Ion - Exchange Method

Anion - exchange resins ine hukama hwakasimba hwesimbi dzakasiyana-siyana - cyanide complex ions mucyanide - ine tsvina yemvura. Kuburikidza nemaitiro eadsorption uye desorption, Cyanides uye simbi dzinokosha mumvura yakasviba dzinogona kubviswa. Kubatsira kweiyi nzira ndeyekuti mvura yakanatswa yakanaka uye yakagadzikana. Nekudaro, anion - exchange resins ine diki diki saizi uye isina kukwana mechanical simba. Uyezve, maitiro acho akaoma kunzwisisa, ane dambudziko guru rekushanda uye mari yakakwirira.

Yakashandiswa Carbon Adsorption Method

Activated kabhoni ine yakapfuma microporous chimiro uye pamusoro hydrophobicity, uye ine yakanyanya kusimba hukama hwechepfu mumvura. Naizvozvo, iyo activated kabhoni adsorption nzira yagara iri imwe yedzakanyanya nzira yekubvisa yakaderera-inokonzera chepfu mumvura. Iyo adsorption maitiro eiyo activated kabhoni inonyanya kuenderana neayo akawanda emukati pores uye yakakura chaiyo nzvimbo.

Kuti ave nechokwadi chokuti cyanides dzakadai Sodium Cyanide isina kudonha, vaongorori vanogara vachiyedza huwandu hwemvura kuti vaone huwandu hwekusvibiswa kwecyanide. Kana zvichidikanwa, nzvimbo yambiro inowedzerwa. Vese vaongorori uye vari pa - vashandi vekurapa saiti vanofanirwa kupfeka mafuta erabha - anodzivirira magirovhosi ekudzivirira.

Mukupedzisa, kurapwa kwakakodzera uye kudzokororwa kwe Cyanide tsvina mvura zvakakosha pakuchengetedza kwezvakatipoteredza uye kuchengetedza zviwanikwa. Nekushandisa nzira idzi uye nekuona kutariswa kwakasimba, tinogona kuderedza kuipa kwecyanide - ine tsvina pane zvakatipoteredza uye hutano hwevanhu.
