Synchronous treatment of heavy metal ions and nitrate by nanoscale zero-valent iron (Fe0)(纳米级Fe0同步处理重金属离子与硝酸根的研究)

纳米级零价铁(Fe0)同步处理Cu2+、Ni2+、Cr(VI)等重金属离子和硝酸根的实验中发现,硝酸盐对重金属离子的去除基本无影响,而不同重金属离子则对硝酸盐的去除有不同的影响.同步去除Cu2+和NO3-、Ni2+和NO3-时,与单独去除NO3-相比,Cu2+、Ni2+可以明显地提高硝酸盐的去除率和反应速度,并且Cu2+、Ni2+的初始浓度越高,NO3-的去除效果越好,反应速率常数kobs也越大.纳米级Fe0同步去除Cr(VI)和NO3-时,Cr(VI)阻碍了Fe0还原脱除硝酸盐反应的发生,当Cu2+、Ni2+或Cr(VI)的初始浓度为20 mg • L-1时,纳米级Fe0去除NO3-的反应速...
