Unyango lwamanzi amdaka ane-chromium kwi-elektropla

Thelekisa iziphumo zonyango ze-sulfate ye-sulfate kunye ne-sodium bisulfite

Inkqubo yemveliso ye-elektronisi kufuneka ichithwe, kwaye kwinkqubo yokucoca i-cenrofawa, ke amanzi amdaka aya kuvelisa inani elikhulu le-chromium-enamanzi amdaka eChromium. I-chromium kumanzi amdaka ane-chromium ine-hexavalent chromium, enetyhefu kwaye kunzima ukuyisusa. I-Hextavalent Chromium ihlala iguqulwa ibe yi-chromium eninzi kwaye isuswe. Ukususwa kwe-chrome ye-elektrome-equkethe amanzi amdaka, ukuqunjelwa kweekhemikhali kunye nobuqili kuhlala kusetyenziswa ukuyisusa. Iqhelekile isetyenziselwa i-sulfate ye-sulfate kunye nendlela yokunciphisa i-lime kunye ne-sodium bisulfite kunye nendlela yokunciphisa i-alkali.

I-1. I-Sulror Sulfate kunye neNdlela yokuNgcali kweLime

I-sulfate ye-sulfate yindawo eyomeleleyo ye-acid i-ocidation ye-oxidation eyomeleleyo. I-sulfate ye-sulfate inokuncitshiswa ngokuthe ngqo i-hextavalent chromium emva kwe-hydrolysis kumanzi amdaka, i-9, kwaye ikwazi ukuncedisa i-CHROIIUR TOORTE, i-CHROMATION SORTE, isiphumo sokukhupha i-chromate sinokufikelela malunga ne-94%.

I-Sulror Sulfate Polfate Plus Sciection Ukunciphisa i-chromate chromate inesiphumo esihle kwi-chromium shokoxa kunye neendleko eziphantsi. Okwesibini, akukho sidingo sokuhlengahlengisa ixabiso le-pH ngaphambi kongezwa kwenkunkuma enobunzima, kwaye idinga kuphela ukongeza i-lime ukulungelelanisa ixabiso le-pH. Nangona kunjalo, ngenxa yenani elikhulu le-slarling palfment yenzekile nokubangela ukwanda okukhulu kudaka lwensimbi, ukwandisa iindleko zonyango.

I-2 ,.Sodium Bisulfite kunye ne-Alkali yokuNikezela

I-Sodium Bisulfite kunye ne-Alkali yokuncitshiswa kwe-chromate chromate, i-PH yamanzi amdaka alungiswa kwi-≤2.0. Emva koko i-sodium bisulfite yongezwa ukunciphisa i-chromate ukuya kwi-chromium ye-stridiba, kwaye ixabiso lenkunkuma lingena kwitanki elilawulayo, kwaye ixabiso lenkunkuma lilungiswa kwi-chiement, kwaye iqondo lokukhupha lifike malunga I-95%.

Indlela ye-Sodium Bisulfite kunye ne-Alkali yokunciphisa i-chromate ilungile ekususweni kweChromium, kwaye iindleko zayo ziphezulu kakhulu kune-sulrous yexesha elinobunzima, kwaye ixabiso le-PH lifuna ukulungiswa nge-acid ngaphambi konyango. Nangona kunjalo, xa kuthelekiswa nonyango oluqinileyo lwe-culfate, ngokusisiseko aluveli isambuku esikhulu kakhulu, ukunciphisa iindleko zonyango, kwaye isambatho esiphathwayo sinokusetyenziswa kwakhona.
