| 摘 要： | 以TEOS为原料,将其与AlCl_3溶液混合后再缓慢滴加Na0H溶液,合成出具有不同Si/Al比和B值的复合絮凝剂样品TEOS-PAC。用Ferron逐时络合比色法对其Al形态分布及转化特征进行了研究,并与以硅酸钠(Na_2SiO_3·9H_2O)为原料相同条件下制备的样品作了比较,初步得出了Si/Al比和β值对TEOS-PAC复合絮凝剂中Al形态的影响规律。

| Abstract: | A series of coagulant (PAC-TEOS), with different basicity (B) and Si/Al molar ratio has been prepared. The polyaluminum species distribution and transformation in PAC-TEOS solution were studied by means of ferron timed complexation spectrophotometry. This pattern that B value and Si/Al molar ratio affected the Al species distribution was obtained initially. |
