Abstract :The electrochemical behaviour of linear alklybenzene sulfonate insert ignore into journalissuearticles values(LAS); on Pt electrodes was investigated in 0.05M Na2SO4 and in 0.1M NaCl at pH=8 by the potentiokinetic method and by electrolysis. The anodic and cathodic semilogarithmic current-potential curves were obtained between -1.6V - +1.6V. The experimental discharge potentials were determined by means of current-potential-curves obtained by electrolysis between 0-3V. The percentages of surface active material remaining in the solution after specified periods insert ignore into journalissuearticles values(0-6hrs); were determined for different initial concentrations of LAS insert ignore into journalissuearticles values(30, 150, 300 ppm); by using a potentiostat at +1.6V and by applying a potential of 20V via a direct current source. The concentrations of LAS in the solution were determined with a UV spectrophotometer. The results indicate that when a potential of 20V is applied on the electrodes the concentrations of surface active materials insert ignore into journalissuearticles values(LAS); decrease by 40-50% at the end of 6 hours in 0.05M Na2SO4 solution.
