摘要: 本文首先介绍了水中重金属离子对环境和人体的危害，然后分析讨论了活性炭对污水中重金属离子的吸附作用。活性炭对重金属离子的吸附多为化学吸附和单分子层吸附，文中重点阐述了活性炭对铬离子、铜离子、镉离子的吸附机理，不同的吸附条件对重金属离子的吸附效果影响显著，因而还讨论了活性炭对重金属离子吸附脱除的优化条件。此外，还综合分析了活性炭的研究现状并对其未来的研究和发展提出了展望。
Abstract: This paper introduces the harm of heavy metal ions to the environment and human body, and an-alyzes the adsorption effect of activated carbon on heavy metal ions in sewage. The adsorption mechanism of activated carbon on chromium, copper and cadmium ions was expounded, and the optimal adsorption conditions were discussed. For modified activated carbon, the adsorption methods are mostly chemical adsorption and monolayer adsorption. Different adsorption condi-tions have a significant effect on the adsorption of heavy metal ions by activated carbon. In addition, the research status of activated carbon is objectively analyzed and the future research and development are prospected.
