中文摘要：将膨润土改性,制得羟基铁柱撑膨润土(OH-Fe-PILC)、羟基铝柱撑膨润土(OH-Al-PILC)和羟基铁铝复合柱撑膨润土(OH-Fe-Al-PILC)。研究表明:柱撑膨润土的层间距比原土的明显变大,在实验条件下对磷的吸附能力为:OH-Fe-Al-PILC>OH-Fe-PILC>OH-Al-PILC;对10mg/L的含磷废液的去除率分别为97.8%、97.7%和93.4%;对50mg/L的含磷废液的去除率分别为92.0%、87.3%和65.5%。

外文摘要：Three absorbents hydroxy-iron-pillared bentonite, hydroxy-alumina-pillared bentonite, hydroxy-iron-alumina-pillared bentonite were prepared via ion exchange reaction. The research result showed that the interlayers of absorbents became bigger. The abilities of phosphorus adsorption for three absorbents were as following： hydroxy-iron-alumina-pillared bentonite 〉 hydroxy-iron-pillared bentonite 〉 hydroxy-alumina-pillared bentonite. The maximum removals were 97.8%,97.7% and 93.4% for 10mg/L phosphate solution.When the solution concentration was 50mg/L,the maximum removals were 92.0%,87.3% and 65.5%.
