Abstract

The sediments from Yinchu Lake and Liwa River were studied for the effects of redox changes on Zn and Fe transformation. A simulated experiment was conducted with 4 different redox treatments：aerobic (+O), anaerobic (-O), aerobic then anaerobic (+O→-O) and extensively anaerobic (--O). Compared with anaerobic condition (-O), percentage of oxidizable Fe decreased from 5.53% to 4.60% in the sediment from Yinchu Lake under aerobic condition, while reducible and residual Fe increased from 13.77% to 16.20% and from 81.08% to 83.49%, respectively. Furthermore, the concentration of Fe release in the supernatant was decreased. Percentage of Zn in acid extractable, reducible and FeMn oxides fraction were respectively declined from 30.14% to 29.16%, from 25.40% to 23.90% and from 35.73% to 32.72% in the sediment from Yinchu Lake. However, Zn in residual fraction rose from 32.73% to 35.92% after treated with oxygenenation, which decreased the concentration of Zn release in the supernatant. It indicated that Fe and Zn in FeMn oxides fraction and organic matter fraction had good corrections with each other. Our study would provide scientific basis for risk analysis and evalution on eutrophicated urban river in the process of ecological restoration.
