摘要

Here, we report the removal of chromium from landfill leachate by electrocoagulation (EC) using ironand aluminum electrodes and a solar panel as the electrical energy source. Two rectangular plates ofaluminum and iron were used as cathode and anode, respectively. Different kinds of operationalparameters such as contact time, pH, inter-electrode distance and current density were investigated andoptimized to obtain the best process function. Based on the findings, the removal efficiency of chromiumincreased by increasing the current density and the reaction time and decreasing the distance betweenthe electrodes. The experimental results indicated that the removal efficiency of chromium of 98.0%from raw leachate was obtained under the optimized conditions of current density 4.5 A/m 2 , initial pHof 3, contact times 27.0 min and the electrode-distance of 0.5 cm.
