Abstract

Electrolytic method is applied to recover nickel from the simulated nickel-containing electroplating wastewater. The experiment studied the main parameters affecting the recovery of nickel, including titanium plate, titanium mesh and graphite as cathode materials, other parameters such as initial concentration of nickel ions, voltage, plate distance, temperature and initial pH value. During the experiment, changing one parameter and keeping the other parameters constant for 6 hours and the recovery and current efficiency are used as evaluation indexes to describe the results of experiment. It’s noticed that titanium plate is the optimum cathode and under the condition of initial concentration of nickel ions 20g/L, voltage 4.0V, plate distance 15mm, temperature 50 and initial pH value 7.0, the recovery efficiency reaches the maximum of 73.12% and the current efficiency is 59.26%.
