A Technique Method of Recycling Waste Liquid in the Sulfate Copper Plating Technological Experiment in the Laboratory

Article Preview

Abstract:

It introduces a kind of technique method that recycling waste liquid in the sulfate copper plating technological experiment in the laboratory, involving the fields in electroplating and comprehensive utilization of waste liquid. This process includes the following steps: first filter the waste liquid to remove impurities in it, and then using electrolytical method to recycle copper in the waste liquid. Add NaOH, NaHSO3 into the solution, through chemical deposition remove heavy metal ions in the waste liquid, and carry on the harmlessization handle to sediments, finally deal with the waste liquid through a semipermeable membrane to get pure water. This process provides a kind of simple, easy to operate, low cost method for the treatment with waste liquid of electroplating produced in the laboratory, which is toxic and pollute the environment.
