土壤对氟离子的吸附和释放实验研究

EXPERIMENTAL STUDY ON SOIL ABSORBTION AND RELEASE OF FLUORIDE

实验研究了土壤中的粘土矿物对氟离子有良好的交换吸附作用 ,用饱水动态土柱法对氟离子进行交换吸附处理可使含氟 1.6 mg/ l的饮用水降到 0 .2 mg/ l,并且水的各项指标均达到国家饮用水标准 ,是降氟的很好材料 。

WT5BZ]The experiments show that clay mineral is a good sorbent for fluoride which is reduced from 1.6mg/l to 0.2mg/l through the soil column, then the water quality reaches the national drinking water standards. The clay mineral is a good material for degradation of fluoride, and will play a great role in improving water environment.
