【 摘 要 】

Aluminium modified zeolite was prepared by acids, bases and their salts and it was used in the adsorption experiments of fluorine-containing water. Through the experimental study on the treatment of fluorine-containing drinking water by modified zeolite, the optimal preparation conditions of modified zeolite and the treatment effect of zeolite fluoride removal were explored. The results show that the Al-modified zeolite has a better adsorption effect on fluorine. When the Al-modified zeolite is used to treat the water which has a fluorine concentration of 1.63 mg/L, the fluoride ion can be reduced to less than 1 mg/L to meet the national drinking water standard.
