| 摘 要： | 采用溶胶-凝胶法制备分子筛／γ-Al2O3复合材料，以高碘酸钾分光光度法为检测手段，考察了分子筛／γ-AL2O3在静态条件下对Mn^2＋的吸附性能。结果表昵，pH值在7～8时，分子筛／γ-Al2O3对Mn^2＋有较好的吸附性能，吸附符合Langmuir吸附模型，吸附容量可达29mg／g，产生复合效应。

| Abstract: | The adsorbability of the zeolite/γ-Al2O3 compound material prepared by sol-gel method under static condition to Mn^2 ＋ was detected by potassium periodate spectrophotography. The result showed that the adsorbability was obtained for Mn^2 ＋ within pH of 7 ～8, the adsorption equilibrium data were well fitted with Langmuir equation, the absorption capacity was up to 29 mg/g induced by composite fuetion. |
