摘要

The efficiency and kinetics of the removal of copper and iron contamination froma chromic acid plating bath were evaluated using a proprietary electrodialytic purification unit with caustic catholyte. The unit consisted of an anode compartment and a cathode compartment separated by a cation-specific membrane. The proprietary electrodes in each compartment were connected to a constant amperage, variable voltage power supply. By design, multivalent metal cations were electrotransported through the membrane and converted into insoluble hydroxides upon reaction with cathode formed hydroxyl ions and other insolubilizing agents present in the proprietary catholyte solution. Threshold Contaminant Levels (TCLs) were approximated using the Hull Cell test apparatus and sample metal concentrations were measured using atomic absorption spectrophotometry.
