EFFECT OF POLYATOMIC ALCOHOLS ON CHROME CURRENT OUTPUT AT ELECTROCHEMICAL WASTE WATER PURIFICATION
Waste water is generated in almost all industrial enterprises and is contaminated with various organic and inorganic impurities and some heavy metals to varying degrees. The aim of this study is to study the effect of polyhydric alcohols on the current efficiency in the electrochemical method of purification of industrial wastewater contaminated with various heavy metals, in particular chromate ions. The current efficiency of chromium does not exceed 18% during the electrolysis of wastewate, during the process in the presence of xylitol in an amount of 0,16%, the current efficiency increased by 21,9%, in the presence of glycerin in an amount of 0,18%, the current efficiency increased by 23,1%, in the presence of ethylene glycol in the amount of 0,20%, the current efficiency increased by 24,2%
