Abstract:
Electroplating is widely used to improve corrosion resistance, hardness, and decorative value. In some cases, several metals are coated on product surfaces. Wastewater from the electroplating industry is commonly composed of toxic heavy metals. At low metal-ion concentrations, adsorption is one of the most effective treatment methods. SBA-15, MCM-41, and silica aerogel were selected due to their different structures. These materials were modified with EDTA (ethylenediaminetetraacetic acid) to study the adsorption of copper, nickel, and chromium ions. It was found that the adsorption capacities of these silica materials were close. Moreover, removal efficiency decreased with increasing initial metal concentration. Finally, the experimental data agreed well with both Langmuir and Freundlich isotherm models, with the Langmuir model providing a better fit. Using EDTA-modified SBA-15, the maximum adsorption capacities of copper, nickel, and chromium ions were 97.09, 93.46, and 163.93 mg/g, respectively.
