Nickel Removal from Rinse Waters Generated by Electroplating Industry Using a Rotating Cylinder Electrode (RCE) Reactor

摘要

This work shows the application of a rotating cylinder electrode (RCE) in the removal of Ni(II) content from an industrial effluent. The study was initially performed in model solution [Ni(II)]=1200 ppm = 0.02M. The model solution was prepared according to the physicochemical properties determined from rinse water from the electrolytic nickel process generated by a plastics chromium-plating industry. The operational conditions were determined from microelectrolysis (stainless steel 316L, RDE) characterization of this model solution. The recovery of Ni(0) in the RCE (SS 316L) was achieved at speed rotations within 300 < olysis for
