Abstract

In this study, removal of linearalkylbenzenesulphonate (LAS), which is one of various water pollutants, by means of electrocoagulation has been. investigated using polarization method with iron and aluminium electrodes in 0.1 M NaCl solutions at pH 8 containing 0, 30, 150 and 300 ppm LAS. A constant anodic potential of +1.6 V has been applied to the test cells by means of the potentiostat and the amount of LAS remaining in solution has been determined by U.V. spectrophotometer. The results show that the Al+3 ions produced electrochemically are more effective in the electrocoagulation of LAS than the Fe+3 ions.
