去除水体中 F-和 SO2-4的吸附材料
Materials of Adsorbing Fluoride and Sulfate in Water
摘要
Abstract
Four kinds of adsorption materials-scoria,bone char,ash and manganese sand were used to remove F- and SO 2 -4 in water.The research results show that adsorption capacities of scoria and bone char for F- were 0.092,0.041 mg/g;adsorption capacities of them for SO 2 -4 were 5.72,3.99 mg/g. Adsorption capacities of ash and manganese sand for F- were both below 0.020 mg/g.And SO 2 -4 was almost not adsorbed by them.Modification was applied in scoria and bone char because of their good adsorption effects.The research results show that Al2 (SO 4 )3 could be used as modifier.Adsorption capacity of scoria which was soaked in 10% Al2 (SO 4 )3 then calcinated at 300 ℃ was the maximum 0.099 mg/g.Adsorption capacity of scoria which was soaked in 10% Al2 (SO 4 )3 was the maximum 5.93 mg/g.Adsorption kinetics of them both followed quasi-secondary dynamics equation.关键词
