The highly efficient inorganic polymer flocculants （IPFs） of the ferric-silica system is a new and promising coagulant. Interactions between ferric species and silica play a large part in the coagulation of suspensions. These effects are quite distinct from those associated with polymeric or colloid silica. However, although these species are key to coagulation efficiency, they have not been comprehensively discussed. A new type of coagulant, poly-silica-ferric-chloride （PFSC）, was synthesized by co-polymerization and characterized by time complexation spectroscopy and photon correlation spectroscopy. Compared with traditional ferric salt, the results indicated that PFSC had a higher molecular weight, lesser positive charge, lower Feb and higher Fec. The higher the Si/Fe ratio, the higher the silica and lower the silicac found. The PFSC with appropriate polysilica acid not only obtained better coagulation/flocculation efficiency in turbidity removal, enhanced the flocculation index （FI） and provided less residual ferric, it also lowered water treatment costs compared to traditional ferric salt. Results showed that PFSC could remove colloid particles in water by charge neutralization and sweeping, adsorption bridging mechanism.

利用水玻璃制备了具有较佳形态的活性硅酸,研究了该活性硅酸对不同B值铝盐助凝时模拟体系的混凝行为.结果表明:该活性硅酸具有明显的助凝效果;当有活性硅酸助凝时,体系Zeta电位明显降低,而除浊效率得到明显提高;有活性硅酸参与下的混凝机理有别于单纯铝盐,活性硅酸的介入会削弱铝盐在混凝中的电中和作用,但同时强化了黏接架桥与网捕卷扫的作用机制.

双酚A是一种典型的环境激素,广泛存在于人类的生活之中,对人类的生活有着极其深远的影响。本文通过GAC、CAC和PAC 3种活性炭分别吸附双酚A的行为分析,考察活性炭对双酚A的吸附能力。用一级动力学方程、二级动力学方程、Elovich方程、双常数方程和扩散方程对实验数据进行拟合,选择实验平衡浓度较理论平衡浓度的差异来评价模型拟合度,得出二级动力学方程能够很好地描述3种活性炭吸附双酚A的行为。此外,Elovich方程的拟合效果也比较理想,说明吸附过程为先快吸附后慢吸附,得出吸附双酚A的能力为:CAC>PAC>GAC。

Chiral Mn Ⅲ (salen) (Jacobsen's catalyst) was axially immobilized onto a new type of organic polymer-inorganic hybrid materialzirconium poly(styrene-isopropenyl phosphonate)-phosphate(ZPS-IPPA) with different linkage lengths and evaluated as catalysts for the epoxidation of unfunctionalized olefins. The results demonstrated that the prepared catalysts exhibited moderate to good activity and enantioselectivity in the asymmetric epoxidation of unfunctionalized olefins. Furthermore, the immobilized catalysts were relatively stable and could be conveniently separated from the reaction system by simple precipitation in hexane. Moreover, higher enantioselectivity was obtained with catalyst 2c than that of homogeneous counterpart catalyzed even after eight times. The excellent recycling of the catalyst was attributed to its structure feature of ZPS-IPPA which is different from either pure polystyrene or pure zirconium phosphates.
