摘　　要：采用加入蔗糖法制备超微5A分子筛,用于处理废水中铬离子。结果表明,超微5A分子筛对废水中铬离子具有很强的吸附性能,最大吸附量为37 mg/g;超微5A分子筛对铬离子的吸附满足Langmuir吸附等温式,其吸附速率满足二级吸附速率方程。Using sugar method to prepare ultramicro 5A molecular sieve,and uses it to treat Cr^3+in waste water.The results show ultramicro 5A molecular sieve has strongly and quickly adsorptivity.The maximum adsorption of chromium ion on utramicro 5A molecular sieve is 37 mg/g.The adsorption of chromium ion on utramicro 5A molecular sieve meets the Langmuir isotherm,and the adsorption rate meets the 2 Grade adsorption rate equation.
