摘要:
Batch experiments were conducted under static and dynamic conditions respectively to explore the mechanism and kinetics of U(VI) immobilization by zerovalent iron (ZVI) and the impact of pyrite. The dynamic results suggest that the U(VI) immobilization reaction by ZVI shows pseudo-first order with respect to U(VI) concentration. When the initial U(VI) concentration increased from 50 to 300mg/L at a fixed ZVI loading (2%), the rate constantly decreased from 0.1776 h(-1) to 0.0177 h(-1). The static results show that ZVI system removed U(VI) very quickly whereas the FeS(2) system did the most slo...
