Removal of Ni2+ and catalytic dechlorination of chlorophenol from contaminated water by zero-valent iron(零价铁去除水中Ni2+及对有机氯脱氯的催化作用)
Abstract
为考察零价铁(Fe0)修复Ni2+污染水体的效果及同步修复Ni2+和有机氯的可能性,考察了 Fe0对水中Ni2+的去除效果及Ni2+对有机氯脱氯的催化作用.实验结果表明,Fe0除镍反应符合拟一级反应动力学特征,表观反应速率常数(kobs)随铁粉颗粒粒径的减小而增大,铁粉颗粒粒径由2. 000〜0. 425,0. 425〜0. 150,0. 150〜0. 075减小到80%),这为Fe0修复技术的实际应用奠定了基础.
