Pak, D Chung, DW Ju, JB 2024-01-21T13:04:40Z 2024-01-21T13:04:40Z 2021-09-04 2001-01 0043-1354 https://pubs.kist.re.kr/handle/201004/140831 An electrochemical reactor was designed and operated to treat the solution containing copper ions. Design parameters for the electrochemical reactor using the porous cathode and RuO2/IrO2/Ti anode were investigated. The porous cathode was prepared by the electroless nickel deposition on polyurethane. The apparent current, the gap between cathode and anode, and hydraulic retention time (HRT) were selected as design parameters. The copper removal rate increased with an increase in apparent current. It was not affected by the gap between the cathode and the anode. A reduction in hydraulic retention time stimulated the mass transfer toward the electrode and increased the cathodic current efficiency. Dimensional analysis was conducted to obtain the design equation for scale-up of the electrochemical reactor. The dependence of Sh on Re, Sc, and characteristic lengths, D-C/A/L and D-W/C/L, was described in the form of a power series. The coefficients were obtained from experimental data.
