| 中文摘要: |
| 合成了淀粉(St)-丙烯酰胺(AM)-丙烯羟肟酸(AHA)接枝共聚物。考察了该聚合物投加量、pH值、反应时间对水中重金属离子Pb2+脱除效果的影响。结果表明:pH=7~9,聚合硫酸铁投加量10mg/L,接枝共聚物的投加量250~300mg/L时,该共聚物对水中Pb2+的去除效果良好,去除率≥99.5%,而且该共聚物还具有良好的除浊能力。 |
| 英文摘要: |
| In this study, the graft copolymer of starch acrylamid and propylene hydroxamic acid is synthesized and the effect of the dosage of the graft copolymer, its pH value and its reaction time on the removal of the heavy metal ions Pb2+ from water is examined. The results show that the optimum conditions for the removal of Pb2+ from water are as follows:PH is7~9, the dosage of polymeric ferric sulfate is 10 mg/L, and the dosage of graft copolymer is between 250 and 300 mg/L. The removal rate is greater than 99.5% and the copolymer also has a good capacity for turbidity removal. |
