Study on Electrochemistry Property of Ferric(III)-Oxalate-Gluconate Complex and its Dyeing Application

Abstract

The electrochemistry property of the ferric-oxalate-gluconate complex was investigated using a gold electrode as working electrode. The peak currents of the ferric-oxalate-gluconate complex were found to increase linearly with square root of scanning rate displaying a quasi-reversible cyclic response of the redox process. The optimal conditions could be drawn from the cyclic voltammetry results and K/S values. That is 8.00 g/L ferric sulfate, 10.08 g/L oxalate, 17.92 g/L calcium gluconate and 45.00 g/L sodium hydroxide. Under this condition, we can not only get high reducing strength in the electroanalysis process, but also have cotton fabrics with good dyeability.
