Adsorptive Stripping Voltammetric Study of the Enhancement of Copper(Ⅱ) in Phosphate and Carbonate media and in the Presence of Silicate

Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080

Received Date: 23 August 1996

Adsorptive enhancements of several inorganic salts on copper(Ⅱ) were studied by adsorptive stripping voltammetry with a hanging mercury drop electrode.Increases in peak current of Cu(Ⅱ) were observed in alkaline phosphate or carbonate media owing to adsorption.Silicate can also enhance the peak current of Cu(Ⅱ).The enhancing power of phosphate,carbonate,and silicate is 33,26,and 8.9 times,respectively.
