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

Kedu ka sodium cyanide si egbu egbu?

sodium cyanide bụ kristal ọcha ntụ ntụ ma ọ bụ granules nke bụ hygroscopic ma na-esi ísì ụtọ almond. Ọ na-agbaze nke ukwuu n'ime mmiri ma na-eme ngwa ngwa hydrolyzes ka ọ bụrụ hydrogen cyanide, ebe ngwọta mmiri ya bụ alkaline siri ike. Ọ bụ ihe dị mkpa na akụrụngwa akụrụngwa. N'ụzọ doro anya, ọ na-egbu egbu nke ukwuu; ịkpọtụrụ ọnya akpụkpọ ahụ, iku ume, ma ọ bụ iri ọbụna ntakịrị ntakịrị nwere ike ibute nsị na ọnwụ.

N'iji LD50 nke a na-akpọkarị (ọgwụ a chọrọ iji gbuo ọkara nke anụmanụ ule n'ime oge a kapịrị ọnụ), 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.

Ọbụna ihe na-atụ egwu bụ eziokwu ahụ bụ na ndị a na-egbu egbu cyanides igbari ngwa ngwa na mmiri, na-eduga ngwa ngwa mmetụta. Ọnwụ nwere ike ime n'ime nkeji iri na ise ruo elekere 15, na-ahapụ ndị ọkachamara ahụike nwere obere oge maka nnapụta.
