Study on electrochemistry property of Ferric(Ⅲ)-Oxalate-Gluconate Complex and Its dyeing application

摘要

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.
