摘要
Abstract
The cyclic voltammetric curves of the ferric-oxalate-calcium gluconate and the ferric-TEA-cal-cium gluconate medium systems were investigated using a glassy carbon electrode as working electrode, and the redox properties of the two systems were also explored. The ferric-oxalate system was unstable under alkaline condition. However, in the presence of calcium gluconate, ferric-oxalate system exhibited good stability in strongly alkaline (pH≥13) media. Moreover, both systems displayed a quasi-reversible reaction which was controlled by diffusion. When the molar ratio of n(oxalate):n(Fe3+):n(DGL) was 2:1:1, the redox potential of the electrolyte achieved -1 019.2 mV after 30 min of electrolysis. Color depth was characterized by the K/S value and CIELab, and the dyeing result was comparable with the conventional samples dyed using sodium dithion-ite as the reducing agent.关键词
