The effect of electrodeposition time on CuCl anodes from waste copper etchant

Potentiometric redox sensing in solutions containing multiple redox molecules was evaluated using in-house constructed nanoporous gold (NPG)-platinum (Pt) and unmodified NPG electrodes. The NPG-Pt electrode was fabricated by electrodepositing Pt into the nanoporous framework of a chemically dealloyed NPG electrode. By varying the concentration of the Pt salt and the electrodeposition time, different amounts of Pt were introduced. Characterization by SEM shows the pore morphology doesn’t change with the addition of Pt and XPS indicates the electrodes contain ∼2.5–24 wt% Pt. Open-circuit potential (OCP) measurements in buffer and solutions containing ascorbic acid, cysteine, and/or uric acid show that the OCP shifts positive with the addition of Pt. These results are explained by an increase in the rate of the oxygen reduction reaction with the addition of Pt. The overall shape of the potentiometric titration curves generated from solutions containing one or more bioreagents is also highly dependent on the amount of Pt in the nanoporous electrode. Furthermore, the generation of OCP vs Log [bioreagent] from the results of the potentiometric experiments shows an ∼2-fold increase in sensitivity can result with the addition of Pt. These results indicate the promise that these electrodes have in potentiometric redox sensing.

Abstract The aims of this research to determine of the optimum of formaldehyde concentration, teh optimum of electrodeposition time and the optimum pH of solution. In addition, this research also aims to determine the character Cu deposite at optimum operational. The sample in this research was used real electroplating liquid waste from Kotagede Yogyakarta.done at various formaldehyde concentration Electrodeposition was done at various formaldehyde concentration, electrodeposition time and varoius of pH. The optimum conditions could be seen the maximum efficiency. It could be obtained by measuring the final concentration of Cu2+ after electrodeposition process by Atomic absorption spectrophotometry. The character of deposit could be seen by visual and X-ray Diffraction. The result of this research showed that the optimum of formaldehyde concentration as reducing agent was 0.3 M. the optimum time was 4 hours and the optimum of pH 9. The character of deposte was contained Cu deposite and more subtle than deposite which electrodeposited without formaldehyde. Keywords: electrodeposition, formaldehyde, reducing agent

Active Corrosion

The present study investigated the active corrosion protection provided by superhydrophobic cerium stearate coatings. Superhydrophobic cerium stearate was deposited on anodized AA 2024-T3 at 40 V with different electrodeposition times using a simple DC electrodeposition technique to know the role of electrodeposition time on surface morphology, hydrophobicity, and corrosion resistance. We characterized the structure and morphology of cerium stearate to understand its formation mechanism. Electrodeposition process at 40 V for 120 min resulted in the formation of dual scale Allium giganteum like micro/nano hierarchical texture of cerium stearate with a water contact angle (WCA) of 165 ± 1.6°. The cerium stearate coating obtained for 120 min process time had excellent self-cleaning property and good chemical stability, environmental stability, and mechanical durability acceptable for industrial applications. Electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET) were used to investigate the active corrosion protection of cerium stearate coating. The electrodeposited cerium stearate coating showed active corrosion protection based on self-healing ability by releasing cerium (Ce3+) ions.
