采用前加碱法制备阴离子聚丙烯酰胺絮凝剂(APAM).最佳工艺条件为:ρ(乙二酸四乙酸)=0.1 mg/L,反应温度24～26℃,ρ(引发剂)=22～24 mg/L,w(丙烯酰胺)=24%～28%,ρ(异丙醇)=35μg/L,pH=10,在该条件下可得到粘均相对分子质量达2.1×107的APAM.将APAM用于处理化工污水,当ρ(APAM)=4 mg/L时,污水的浊度去除率为95.04%,CODCr去除率为86.32%.

Anionic polyacrylamide (APAM) of high molecular weight was prepared. The optimal conditions were found as follows: the concentrations of ethylene diamine tetraacetic acid, initiator, isopropanol and acrylamide were 0. 1 mg/L, 22-24 mg/L, 35 μg/L and 24%-28%, respectively, reaction temperature 24 - 26°C , pH = 10. Under these conditions, the molecular weight of the polyacrylamide reached 2. 1 × 107. Application results showed that when the dosage of APAM was 4 mg/L, the removal rates o...
