| Abstract: | Based on the experiments of static adsorption, the removing fluoride performance of NaCl-Al2(SO4)3 composite modifi ed zeolite was studied in this paper. The influence of modifi ed method, pH value, temperature and contact time on removing fluoride were discussed. The results showed that the fluoride removal rate of NaCl-Al2(SO4)3 composite modifi ed zeolite is higher than NaCl modifi ed zeolite. When using 2.5wt% NaCl-Al2(SO4)3 composite modifi ed zeolite, the removal rate of fluoride is over 59.60%, and t... |
