摘要:
A novel photovoltaic energy-sinusoidal alternating current coagulation (PE-SACC) system was proposed for the removal of heavy metal ions (HMs) in electroplating wastewater. A response surface methodology was used to study the combined effect of two factors on removal efficiency (Re) and energy consumption (EEC), and the optimal process parameters were obtained. The morphology, surface element content, crystal structure, and chemical composition of the flocs generated during the electrocoagulation (EC) process were characterized using SEM, EDS, XRD, FTIR, and XPS techniques. The intra-particle ...
