The removal of Styrene Butadiene Rubber (SBR) from aqueous solution by electrocoagulation using different electrodes was investigated. The main objectives of the experiments were to investigate the effects of the various operating parameters on the SBR and chemical oxygen demand (COD) removal efficiency from aqueous solution. The optimal operating condition for removal of (SBR) were : initial pH of 7.1, an initial polymer concentration of 200 mg/L, temperature of 30 oC, current density (25 mA/cm2) and salt concentration of (1.5 g/L) by using iron (Fe), stainless steel (SS) and aluminum (Al) electrodes. The results showed that the removal percentage for SBR and COD were (99.2% and 91.2 %), (99.4% and 93.5%) and (98.9 % and 90.2%) by using (Fe), (SS) and (Al) electrodes at 15 min respectively. The adsorption equilibriums were analyzed by Langmuir and Freundlich isotherm models. It was found that the data fitted to Freundlich (R？2 = 0.954) better than Langmuir (R？2 = 0.777) model. The removal of SBR exhibited a pseudo first order reaction with rate constant (0.191, 0.245 and 0.142 min-1) for Fe, SS and Al electrodes respectivel
