Abstract

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.
