The Technique of Recycling Alkaline Zincate Zinc Plating Waste Liquid in Laboratory

Abstract:

It introduces a kind of technique method that recycling alkaline zincate zinc plating waste liquid in laboratory, involving the fields in electroplating and comprehensive utilization of waste liquid. This method is introduced that with adopting materials such as HCl, NaOH, H₂O₂, activated carbon, dithiocarbamate diethyl ester, chloroform, ammonia and baking furnace, incinerator, pH test paper, for treatment of the waste liquid through some processes like neutralization, filtration, chemistry precipitation, extraction, distillation, burning, so that some recycled substances in it can be reused such as distilled water, zinc oxide, and as to those can not be recycled, carry on the harmlessization handle by incineration or deep bury.
