In this study, the process of electrocoagulation was opted for to optimize for higher removal efficiency of cadmium from wastewater with low energy consumption. In this experiment, the process of electrocoagulation was employed using iron electrodes in a cylindrical reactor for the removal of cadmium from an Aqueous solution. Response surface methodology (RSM) for a four-factorial central composite design (CCD) was applied to study the effects of process parameters on removal efficiency and energy consumption. Maximum Cd (II) removal efficiency of 96.01% was attained on optimization at an applied current of 0.35 A, an initial cadmium concentration of 20 ppm, an application time of 11 min and pH of 8.98. With the help of the obtained 3-D plots, the interaction between the process variables was evaluated. By analyzing the variance (ANOVA), the generated models were validated. The study shows that electrocoagulation can be used as a low-cost, efficient, and promising alternative to conventional technologies used for the removal of Cd (II).

摘要

In this study, the process of electrocoagulation was opted for to optimize for higher removal efficiency of cadmium from wastewater with low energy consumption. In this experiment, the process of electrocoagulation was employed using iron electrodes in a cylindrical reactor for the removal of cadmium from an Aqueous solution. Response surface methodology (RSM) for a four-factorial central composite design (CCD) was applied to study the effects of process parameters on removal efficiency and energy consumption. Maximum Cd (II) removal efficiency of 96.01% was attained on optimization at an applied current of 0.35 A, an initial cadmium concentration of 20 ppm, an application time of 11 min and pH of 8.98. With the help of the obtained 3-D plots, the interaction between the process variables was evaluated. By analyzing the variance (ANOVA), the generated models were validated. The study shows that electrocoagulation can be used as a low-cost, efficient, and promising alternative to conventional technologies used for the removal of Cd (II).
