| 摘 要： | 研究了无机、有机和无机-有机柱撑膨润土对水中C r6 的吸附去除性能。结果表明:三种柱撑膨润土对C r6 的去除效果明显高于膨润土原土,当投土量为8 g/L时,对C r6 的吸附去除率分别为81.03%、95.41%和85.11%;三种柱撑膨润土对C r6 的吸附在60 m in达到平衡;溶液pH对C r6 的去除有一定的影响,在酸性条件下的去除率略大于中性和碱性;温度升高,C r6 的去除率略有下降。

| Abstract: | Adsorption removal property of bentonite pillared by inorganic,organic,inorgano-organic substances respectively for Cr~6 in aqueous solution was studied.The experimental results show that the Cr~6 removal effect of pillared bentonite is higher than that of raw bentonite,and the Cr~6 removal rates of the three plliared bentonite are 81.03%,95.41% and 85.11% respectively when the addition amount of the bentonite is 8 g/L.The adsorption equilibrium to Cr~6 of the three kinds of pillared bentonite is reached within 60 min.The solution pH has a certain influence on the Cr~6 removal effect,and the removal rates at acidic condition are somewhat higher than that at neutral and alkaline conditions.The Cr~6 removal rate is decreased somewhat with the increase in temperature. |
