Kedu uru dị n'iji hydrogen peroxide na-agwọ mmiri mkpofu sodium cyanide?

sodium cyanide bụ kemịkalụ na-egbu egbu nke ukwuu. Mwepu ọ bụla nwere ike imetụta gburugburu ebe obibi na ahụike mmadụ, ọkachasị na-etinye isi mmiri mmiri n'ụlọ.

Hydrogen Peroxide: Onye Nnọchiteanya Oxidizing Dị Ike

Hydrogen peroxide (H_2O_2) bụ mmiri na-enweghị agba, nke na-apụta ìhè nke ama ama maka njirimara oxidizing ya siri ike. Ọ na-achọta ngwa dị ukwuu na mkpochapụ, mkpochapụ ahụike, yana igba ogwu ụlọ ọrụ. Ntughari ya sitere na ike ya isonye na oxidation - mmeghachi omume mbelata, na-eme ka ọ bụrụ onye na-arụ ọrụ dị irè maka ịgwọ ọrịa dị iche iche, gụnyere. sodium cyanide na mmiri mkpofu.

Usoro mmeghachi omume

Mgbe hydrogen peroxide na-ezute sodium cyanide (NaCN) na mmiri mkpofu, mmeghachi omume oxidation na mbibi na-ewere ọnọdụ. Enwere ike ime ka mmeghachi omume kemịkal dị mfe dị ka ndị a:NaCN + H_2O_2 + H_2O \rightarrow NaHCO_3+NH_3

In this reaction, the highly toxic sodium cyanide is transformed into sodium bicarbonate (NaHCO_3), a common substance known as baking soda in our daily life, and ammonia gas (NH_3). Ammonia, being highly soluble in water, initially remains in the aqueous phase of the treated wastewater.
