Photoelectrocatalytic oxidation of metal-EDTA and recovery of metals by electrodeposition with a rotating cathode

In this work, a photoelectrocatalytic reactor with a rotating cathode was designed for the destruction of metal complexes and recovery of liberated metal ions. The effects of rotating speed, current density, initial pH and initial Cu-EDTA concentration on the recovery of Cu and destruction of Cu complexes were investigated. At cathode rotation speed of 100 rpm, initial pH of 3.18 and current density of 0.5 mA/cm2, the recovery percentage of Cu...
