Sodium Cyanide: Isi ihe eji eme ihe na Ngwuputa na n'ofè

Kedu ka sodium cyanide si egbu egbu?

Sodium cyanide bụ ntụ ntụ ọcha ma ọ bụ granules nke nwere hygroscopic ma nwee obere isi almond dị ilu. Ọ na-agbaze nke ukwuu na mmiri ma na-agbanwe ngwa ngwa iji mepụta hydrogen cyanide, mmiri mmiri ya na-abụkwa alkaline siri ike. Ọ bụ ihe dị mkpa maka kemịkalụ dị mkpa. Nke pụtara na ọ na-egbu egbu nke ukwuu; ọ na-emetụ ọnya akpụkpọ ahụ aka, iku ume, ma ọ bụ iri obere ihe nwere ike ibute nsí na ọnwụ.

Site na iji LD50 a na-akpọkarị (ọnụọgụ achọrọ iji gbuo ọkara nke anụmanụ nnwale ahụ n'ime oge akọwapụtara), arsenic nwere LD50 nke 14.6 mg/kg (ọnụ na oke), ebe Sodium cyanide nwere LD50 nke 6.44 mg/kg (ọnụ na oke). Nke a pụtara na Sodium Cyanide dị ihe dị ka okpukpu atọ karịa arsenic.

Ihe na-atụ egwu karịa bụ na cyanide ndị a na-egbu egbu na-agbaze ngwa ngwa n'ime mmiri, na-ebute mmetụta ngwa ngwa. Ọnwụ nwere ike ime n'ime nkeji iri na ise ruo otu awa, na-eme ka ndị ọkachamara ahụike nwee obere oge maka nnapụta. Ma e jiri ya tụnyere ya, arsenic na-arụ ọrụ nwayọ nwayọ; ihe mgbaàmà nwere ike ọ gaghị apụta ruo otu awa mgbe e risịrị ya, ọnwụ nwekwara ike ime ọtụtụ awa ma ọ bụ ọbụna otu ụbọchị mgbe e mesịrị.

Ojiji nke sodium Cyanide nke ụlọ ọrụ mmepụta ihe

N'afọ ndị na-adịbeghị anya, ojiji nke sodium cyanide aghọọla ihe a na-ahụkarị.
