Studies on process parameters for chlorine dioxide production using IrO2 anode in an un-divided electrochemical cell

摘要: Chlorine dioxide is potentially a powerful oxidant with environmentally compatible application in several strategic areas relating to pollution control typically for water disinfection, and its sustained production key factor successful application. Although increased attention has been paid on-line chlorine generation by chemical electrochemical methods, the details are mostly confined as patents. We studied this work of from an un-buffered solution sodium chlorite chloride mixture un-divided cell under constant current mode, view optimize various process parameters, which have direct bearing on formation efficiency laboratory conditions. The effect feed flow rate (10-150 ml min(-1)), pH (2.3-5.0), concentration (0-169.4mM), (0-7.7 mM), applied (100-1200 mA) dissolved ClO(2) gas product-containing was investigated performing single pass experiments, no circulation, set-up Ti/IrO(2) anode Ti/Pt cathode. power consumption were calculated optimized
