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)
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<0.075 mm时，kobs值相应由0. 022 3，0. 053 8，0. 104 8增加到0. 155 0 min-1；在考察的pH范围(2. 5〜10. 0)内, 零价铁对Ni2+保持着较高的反应速率，在酸性条件下，反...
