METHOD FOR THE REMOVAL OF FLUORINE IONS FROM NEUTRAL ELECTROLYTS FOR ZINC ELECTRICAL EXTRACTION
Изобретението се отнася до бърз, опростен и ефективен метод за отстраняване на вредните флуорни йони от разтворите за получаване на цинк чрез електроекстракция, който се състои в това, че към електролита се прибавя алуминиев сулфат (Al2(SO4)3.18H2O) в сухо състояние в количество от 0,006 до 60 g/l,...

| description | Изобретението се отнася до бърз, опростен и ефективен метод за отстраняване на вредните флуорни йони от разтворите за получаване на цинк чрез електроекстракция, който се състои в това, че към електролита се прибавя алуминиев сулфат (Al2(SO4)3.18H2O) в сухо състояние в количество от 0,006 до 60 g/l, с последващо разбъркване на електролита до пълно хомогенизиране, престой в продължение на 1 до 6 h за взаимодействие на флуорните с алуминиевите йони, отдекантиране и филтруване.
The invention relates to a fast, simple and effective method of removal of the harmful fluorine ions from solutions for the production of zinc by electro-extraction, which consists in the fact that to the electrolyte is added aluminium sulfate (Al2(SO4)3.18H2O) in the dry state in an amount of 0.006 to 60 g/l, with post-mixing of the electrolyte until complete homogenization, stay for 1 to 6h for the interaction of fluorine with aluminium ions, elutriation and filtration. |
