Сравнительная оценка эффективности очистки водных растворов от металлов группы железа методами, основанными на окислении примесей металлов

A comparative evaluation of the effectiveness of nonchemical purification of aqueous solutions of metal ions of the iron subgroup (Fe 2+, Ni 2+ and Co 2+) methods based on the oxidation of metal ions, such as cavitation, electroflotation and oxidation of metal ions using a ruthenium -titanium oxide anodes. The degree of extraction of metal ions studied with aqueous solutions of cavitation treatment in installation by using a ruthenium-titanium oxide anodes and comparable reaches 40-90 % on the initial concentration of the solution by metal ions 5 mg/l. Elektroflotation treatment of aqueous solutions without introduction of oxidant and additional pH adjustment is effective for only solutions containing ions Fe 2 +.
