摘要：

In this study, the use of hydrogen peroxide increased the efficiency of electrocoagulation (EC) by 48%. The data on boron adsorption on the released aluminum in enhanced electrocoagulation (EEC) correspond to Langmuir (R-2 = 0.59) and Freundlich (R-2 = 0.68) isotherms. The data on the kinetics of boron removal by EEC were consistent with the Pseudo-first order kinetics kinetic model (R-2 = 0.99). The rate of boron removal in the EEC is 1.85 times higher than that of the EC. The efficiency of EEC in the removal of boric acid under optimal conditions was more than 88%. Also, the cost of electricity consumption in optimal conditions of EEC is about 39% of EC costs. Therefore, the EEC can be used as an efficient and economical technique to treat boron-contaminated water at low concentrations (10 mg/L) and in neutral environments to meet drinking water standards.
