Ka tekanyo ea ho ntša "electroplating pollutant discharge standard" e ntse e le thata le ho feta, joale, phekolo ea metsi a litšila a boima e fetohile sepheo sa tlhokomelo e kholo ea indasteri. Hona joale hangata ho tšoaroa metsi a litšila a tšepe a boima a rarahaneng le a lokolohileng, ao har'a ona, metsi a litšila a rarahaneng a nang le chefo e matla, phekolo e batla e le thata. 'Me ka lebaka la biochemistry e tlaase ea mofuta ona oa boleng ba metsi, kahoo hona joale phekolo e ka sehloohong ea' mele le ea lik'hemik'hale, phekolo e tloaelehileng e bolela ho sebelisoa ha moemeli oa ho senya, tšepe e boima ea tšepe le sodium sulfide le phekolo e meng ea lik'hemik'hale.

Sodium sulfide e na le phello ea collateral breaking le sulfide precipitation ea heavy metal e silafatsang, le theko e tlaase, kahoo indasteri ea hona joale e ho feta ho sebelisa sodium sulfide ho alafa a rarahaneng a litšila tšepe e boima. Pampiri ena haholo-holo e kenyelletsa tšebeliso ea sodium sulfide le ho eketsa mehato, lintlha tse latelang ke tse latelang.

Ha e le hantle, mohato oa tlatsetso oa sodium sulfide o khethoa haholo-holo ho ea ka boemo ba sebele ba setša, tse latelang ke mehato e seng mekae bakeng sa tšebeliso ea mokhoa o tloaelehileng oa phekolo ea likhoerekhoere.

1. Sodium sulfide e kenngoa karolong e ka morao ea tanka e laolang. Hobane sodium sulfide ke tlhaho e ke ke ea sebelisoa tlas'a maemo a acidic, kahoo ho hlokahala ho eketsa alkali pele ho sebelisoa, e le ho thibela tlhahiso ea lintho tse chefo le tse kotsi, empa hape ho etsa bonnete ba hore phekolo e sebetsang, e nang le boemo bo rarahaneng le mahala. state metal ion reaction to sulfide precipitation.

2. Kenya sodium sulfide ka tanka ea ho arabela. Haeba tšimong debugging, maemo a sebele, sodium sulfide ka li ekeletsoa ka e robehileng ka mor'a (alkaline) karabelo letamo, hobane complexation tšepe ion e se e robehile fetoha mahala tšepe ion, kahoo ka letamo karabelo ka mor'a robeha hape eketsa sodium sulfide kalafo. e thusa haholo ho ntlafatsa phello ea kalafo ea litšila tsa tšepe.

3. Eketsa sodium sulfide karolong e ka pele ea tanka ea coagulation. Pele ho kalafo ea coagulation, sodium sulfide e eketsoa ho fokotsa li-ion tsa tšepe. Hobane boholo ba li-ion tsa tšepe li rarollotsoe, kalafo e latelang ea coagulation e ka tsoela pele ho phekola li-ion tse setseng tsa tšepe, e le hore boleng ba metsi bo ka hloekisoa le maemo a tloaelehileng.
