Ọgwụgwọ nke ISTewater nwere Chromium na Electroplating

Tụnyere nke ọgwụgwọ nke sulfate na sodium bisisinite

Usoro nke electroption kwesịrị ga-aga nke ga na-eme ka ọ ga na-eme ka ọ dị ọcha, n'ụzọ bụ isi, ihe elektrọm na-eme ka acommium na-ebute ihe dị ukwuu na Chromium. Chromium na Isthewater nwere Chromium nwere Chromium Chrim, nke bụ ihe na-egbu egbu ma sie ike iwepu. Hexavalent Chrim na-agbanwekarị chwomium trimeria ma wepu ya. Maka iwepụ nke chrome-nwere chrome electroplate, a na-ejikarị eriri na ọdịda iji wepu ya. A na-ejikarị sulfate sulfate na lime na-agbadata usoro na usoro sodium bising na usoro mbelata Alkali.

1.

Ferrous sulfate bụ ọgwụ acid siri ike nke nwere ihe ndị ọzọ na-ebelata. Enwere ike belata sulfate sulfate na hexavalent chromium ozugbo, na-agbakwunye ya na ndapụta chromium na-agbanwe oke na Chromidium hydroxide ga-ezute ihe dịka 94%.

Ferrous sulfate plus lime coagulant mbelata ọkọlọtọ na-enwe ezi mmetụta na mwepụ chromium na ọnụ ala. Nke abuo, odighi mkpa hazie uru ph tupu mgbakwunye nke ferrous sulfate, na naanị mkpa itinye wayo iji dozie uru iji dozie uru nke PH. Agbanyeghị, n'ihi nnukwu ego na-egbu egbu sulfate mekwara nnukwu mmụba na apịtị apịtị, na-abawanye ụgwọ nke ọgwụgwọ sludge.

2, .Ssodium Bisilfite na usoro mgbanwe nke alkali

Sudium Bisilfie na alkali na-ebute Chromate, a na-ahazi PH nke Isthewoter ka ≤2.0. Mgbe ahụ, a na-agbakwunye sodium bissilite iji belata chrom na Tromiment chromium, a na-agbanwe mmiri na-emebi emebi, mgbe ahụ, a na-anyụ mmiri ahụ na-achịkwa chromate, na ọnụego iwepụ nwere ike iru ihe dịka 95%.

Ofzọ nke sodium bisi na mmachi alkali dị mma maka iwepụ chromium, na oge mmeghachi omume dịtụ elu karịa ka ọ dị ogologo, na uru ọgwụgwọ ahụ kwesịrị idozi ya na acid tupu ọgwụgwọ. Agbanyeghị, e jiri ya tụnyere ọgwụgwọ sọlfọ, ọ na-abụkarị nsị dị ukwuu, belata ego nke ọgwụgwọ, na-enwekarị ike idozigharị.
