| 摘 要： | 在水溶液中以过硫酸铵((NH4)2S2O8)和亚硫酸氢钠(NaHSO3)为引发体系，利用原位聚合法合成了聚丙烯酰胺(PAM)氢氧化铁(Fe(OH)3)有机无机杂化型高分子絮凝剂。通过正交实验得到合成杂化絮凝剂的最佳条件为：反应温度40 °C，引发剂质量分数0.5%，丙烯酰胺质量分数30%，反应时间7 h。FT-IR、TGA以及电导率测试结果表明，杂化型PAM链的端基(-SO2-4)与带正电荷的Fe(OH)3胶体粒子通过离子键键合。絮凝实验结果显示，PAM-Fe(OH)3杂化型高分子絮凝剂的最佳质量浓度

| Abstract: | A novel flocculant based on PAM-Fe(OH)3 hybrid was synthesized with a redox initiation system composed of (NH4)2S2O8-NaHSO3. The effects on intrinsic viscosity of PAM-Fe(OH)3 hybrid were studied using orthogonal test method. Results showed that the optimum reaction conditions were as follows: temperature 40 °C, mass fraction of initiator 0.5%, reaction time 7 h, the monomer mass fraction, 30%. PAM Fe(OH)3 hybrid was characterized by FT-IR spectroscopy, TGA, and conductivity measurement. An ionic bond existed between Fe(OH)3 colloid and polyacrylamide(PAM) chains in the hybrid. Flocculation studies showed that the optimal dosage was 40 mg/L and the hybrid flocculant was superior to polyferric sulfate(PFS) or PAM. |
