Pistillata. However, the mean growth rates of S. pistillata in two mesocosms at 25℃ were significantly different. The mean growth rates of S. hystrix in two mesocosms at 28℃ were significantly different and did not show a consistant relationship compared to those of S. pistillata.

Based on the above experiments, the author studied the mixed metallic pillared and modified montmorillonites. The experimental result indicated that the microporous structure of Fe-Al-PLMs was affected by the changing of interlayer Fe-Al polymer with different Fe/Al ratio. But the presence of Al iron was helpful to incorporate Fe iron into interlayer of montmorillonites.. Introducing Zr helped Al-PLMs getting better larger spacing, thermal stability, surface area and pore volumes. Its successful to apply Zr-Al-PLMs to treat wastewater containing Cr iron. The experiment of modifying Al-PLMs by PVA showed that the order of adding starting materials (Al-pillaring solution, PVA, montmorillonite solution) was related to the property of Al-PLMs. The PVA as precursor was beneficial for Al to go into interlayer of the clay and to form larger basal spacing porous clay. The surface area and pore volumes of Al-PLMs increased mainly because of increasing the external surface area and mesoporous volumes after acid-activating. This conclusion confirmed that the microporous structure of pillaring clay depends upon the interlayer pillar.

实验结果表明:在Al-PLMs中引入Fe离子,不同Fe/Al比制得的Fe-Al-PLMs因层间的Fe-Al聚合离子结构不同而影响其微孔结构,但羟基Al离子的存在有利于Fe离子进入蒙脱石层间;在Al-PLMs中引入Zr离子,有助于其层间距、比表面积、孔体积增大,所得Zr-Al-PLMs应用于含Cr废水处理效果显著;PVA改性后的Al-PLMs其物化性质变化与铝柱化剂、PVA溶液、蒙脱石溶液三者不同添加顺序有关,说明PVA的前撑有利于Al进入蒙脱石层间得到较大层间距的Al-PLMs;经酸化处理得Al-acid-PLMs,其比表面积增大以外表面积为主,孔体积增大以中孔为主,这也证实了柱撑蒙脱石的微孔结构取决于其层间的柱化物。
