Sodium Dimethyldithiocarbamate

Sodium Dimethyldithiocarbamate (SDD) 40% Kev daws:

Sodium Dimethyldithiocarbamate (SDD) 40% aqueous tov yog organosulfur hnyav hlau precipitating tus neeg sawv cev. Nws reacts sai nrog divalent thiab trivalent hlau ions thoob plaws pH ntau yam kom ruaj khov, insoluble chelate precipitates.
Piv nrog rau cov txheej txheem nag lossis daus ib txwm siv, SDD tsis tsim cov pa roj hydrogen sulfide hauv cov kua qaub, txo qis kev nyab xeeb kev nyab xeeb hauv cov chaw kho mob effluent. Nws yog muab raws li ib tug ntshiab, amber mus rau daj ntseg kua kua optimized rau ncaj dosing nyob rau hauv tas li ntawd ntws dej khib nyiab systems.
