| 中文摘要 |
| 探讨了当含铅废物中共存其他金属Ca2+、K+、Na+和Fe3+时,高分子螯合剂对捕集效果的影响。实验结果表明,此种螯合剂对铅的去除率在99.7%以上,不受钾、钠和钙离子存在的影响,并且也不受pH值变化的影响;当有铁离子存在时,会降低铅的去除率,但钙离子的共存有利于铅的去除。 |
| 英文摘要 |
| The author has successfully synthesized a type of polymer chelating agent in the laboratory,and has studied the mechanism of the agent capturing heavy metals.Influences of the coexisting ions such as calcium,potassium,sodium and iron on the agent capturing lead ion has been explored.The result showed that the efficiency of the agent capturing lead ion was above 99.7%,and was not affected by the variety of pH value and by the coexisting ions of calcium,potassium and sodium.However,it was found that the efficiency of agent capturing lead ion was reduced by the coexisting iron ion,but was raised by the coexisting calcium ion. This type of polymer chelating agent is proved to be an efficient chemical stabilization agent in capturing lead ions. |
