Application of Electrocoagulation on Adsorption of Styrene Acrylate Polymer from Aqueous Solutions

Abstract

In this paper, the feasibility of electrocoagulation technique for the adsorption of Styrene acrylate SA from aqueous solution has been studied. The results showed that SA and COD removal were (99.2% and 95.9 %), (99.4% and 97.1%) and (99 % and 93.1 %) by using iron Fe, stainless steel S-S and aluminum Al electrodes at 8 min respectively. The adsorption equilibrium were analyzed by Langmuir and Freundlich isotherm models. It was found that the data fitted to Freundlich (R² = 0.944) better than Langmuir (R² = 0.674) model. The adsorption of SA exhibited pseudo first order with rate constant (0.932, 0.913 and 0.942 min-1) using Fe, S-S and Al electrodes. The consumption of electrical energy for SA at optimum conditions as follows: (0.283, 0.243 and 0.18 KWh/m3) using Fe, S-S and Al electrodes respectively.
