6种固化剂对土壤Pb Cd Cu Zn的固化效果OA北大核心CSCDCSTPCD
Effects of Six Kinds of Curing Agents on Lead, Cadmium, Copper, Zinc Stabilization in the Tested Soil
通过在重金属污染土壤中分别施加沸石、石灰石、硅藻土、羟基磷灰石、膨润土和海泡石6种固化剂,研究了这6种固化剂对土壤中Pb、Cd、Cu、Zn的固化效果,筛选出几种效果较好的固化剂.实验结果表明:沸石、石灰石和羟基磷灰石均能够有效地降低土壤中交换态Pb、Cd的含量,并且明显减少了土壤中Pb、Cd的毒性浸出量,其中沸石最多降低土壤中交换态Pb、Cd含量分别达到48.7％和56.2％,减少土壤中Pb、Cd的毒性浸出量达到37.1％和30.1％；沸石、石灰…查看全部>>
The stabilization of Pb, Cd, Cu, Zn in heavy metals contaminated soil was studied by using six kinds of curing agents, namely, zeolite, limestone, diatomite, hydroxyl-apatite, bentonite and sepiolite, and some effective curing agents were picked out. The main results of the experiments were as follows: zeolite, limestone, hydroxyl-apatite could effectively reduce exchangeable contents and leaching solution contents of Pb and Cd in the soil. Zeolite sho…查看全部>>
