| Abstract: | Taking Jinzhou high-quality natural zeolite as raw material,the modification of zeolite is attained by means of vitriol activation,lanthanum nitrate impregnation.The effects of several factors,such as stirring time,pH value of original water and the dose of modified zeolite on removal efficiency of fluorides from groundwater are examined.The test results showed that after treated by means of modified zeolite,the groundwater containing fluorides can reach the national standards for drinking water. |
