СРАВНИТЕЛЬНЫЙ АНАЛИЗ ВЛИЯНИЯ РАЗЛИЧНЫХ ДОБАВОК НА ЭЛЕКТРОФЛОТАЦИОННОЕ ИЗВЛЕЧЕНИЕ ЧАСТИЦ АКТИВИРОВАННОГО УГЛЯ ИЗ ВОДНЫХ РАСТВОРОВ

The results are presented on studying electroflotation extraction of activated carbon (OU-B trademark) particles from aqueous solutions in the presence of various substances, i.e. surfactants of various nature (cationic, anionic and nonionic types), coagulants – trivalent metal ions (Al3+, Fe3+) and divalent metal ions (Co2+, Ni2+, Cu2+, Zn2+), and background electrolyte (Na2SO4). A comparative analysis has been carried out focusing on effect of these additives on efficiency of electroflotation extraction of OU-B particles, wherein the maximum degree of extraction reached 99%. The obtained data can contribute to the development of the process of purifying waste and wastewater of electroplating plants using electroflotation method.
