| 摘 要： | 研究了聚乙烯亚胺（PEI）辅助超滤处理含重金属离子锶（sr2＋）和钴（Coz＋）的废水。重点考察了PEI与重金属离子的质量浓度比（P／M）,溶液pH以及离子强度对sr^2＋和Co“截留率的影响。结果显示PEI去除sr^2＋和Co^2＋的最适pH为5和9,去除两种金属离子的最佳P／M值均为10。在最佳P／M值和最适pH时,对锶和钴的截留率分别为59％和100％。试验结果表明使用PEI辅助可以大大提高超滤膜对重金属废水中Sr^2＋和C0^2＋（尤其是con）的去除效率。

| Abstract: | Polyethyleneimine(PEI) was used in polymer enhanced ultrafiltration to remove strontium ion(Sr2+) and cobalt ion(Co2+) from industrial wastewater.Effects of concentration ratio of polymer and metal ion,pH and ionic strength on Sr2+ and Co2+ removal were investigated.Optimum pH values on Sr2+ and Co2+ removal are 5 and 9,respectively;optimum P / M values are 10 for both metals.Under optimum conditions,removal rates of Sr2+ and Co2+ are 59 % and 100 %,respectively.The results show that PEI enhanced ultrafiltr... |
