摘要

采用液相还原法制备了纤维素稳定的零价纳米铁粒子(ZVI)

并对不同浓度和pH条件下稳定的零价纳米铁粒子去除SeO42-的反应动力学进行了研究.纤维素稳定的零价纳米铁粒子去除SeO42-的初始动力学(t≤8h)反应符合准一级动力学方程.实验结果表明:在相同的实验条件下(pH=7.0

T=25℃)

Kobs的最大值为0.24h-1.研究结果还表明pH值等于6.0是ZVI与SeO42-发生氧化还原反应的最佳pH值.

Abstract

The cellulose stabilized zero valent irion(ZVI) was prepared by liquid phase reduction method.The kinetic property of removal of SeO42- by stabilized zero valent iron(ZVI)nanoparticles was investigated at different initial concentrations and pH values.The initial(t≤8 h) kinetic data

which were gotten from reduction SeO42- by cellulose stabilized ZVI

were fitted pseudo first-order kinetics.The experimental results show that the maximum value of the Kobs is 0.24 h-1 at the same experimental conditions(pH=7.0

T=25 ℃).The results also indicate that the optimal pH value is identified to be 6.0 that ZVI and SeO42- have an oxidation-reduction reaction.
