Batch and Column Experiments on Fluoride Removal from Waters Using Modified Zeolite

摘要

High fluoride groundwater occurs widely in China, presenting a quite serious environmental problem. Zelite from Xinyang, China was tested as the fluoride-removing adsorbent. Batch and column experiments on fluoride removal using modified zeolites treated with hydrochloric acid, sodium hydroxide, sodium chloride and ferric chloride, respectively show that 0.1 mol/L HCI modified zeolite can be used as an adsorbent for fluoride, with an adsorption capacity of 173.16 mg/kg.
