摘要
重金属污染是目前最受关注的环境污染问题之一,由于六价铬(Cr(Ⅵ))污染的剧毒性、难处理性、分布广泛性,备受研究人员的关注。本文包括了活性炭的表面结构、表面性质、各类活性炭对Cr(Ⅵ)的吸附研究现状,以及活性炭吸附Cr(Ⅵ)的影响因素及机理,研究表明,活性炭吸附Cr(Ⅵ)的最佳pH为2左右,且活性炭的微孔和中孔对Cr(VI)的吸附有利,研究了改性活性炭和未改性活性炭对吸附Cr(Ⅵ)的差异。本文可为进一步研究活性炭对Cr(Ⅵ)的吸附提供参考。最后对活性炭的未来研究方向提出了展望。
Heavy metal pollution is one of the most concerned environmental pollution problems at present. Due to the toxicity, refractory and widespread distribution of hexavalent chromium(Cr(VI))pollution, researchers pay close attention to it. The surface structure and properties of activated carbon, the research status of adsorption of Cr(VI)on various activated carbon, and the influencing factors and mechanism of adsorption of Cr(VI)on activated carbon were reviewed. The results showed that the optimal pH of adsorption of Cr(VI)on activated carbon was about 2,and the micropores and mesopores of activated carbon were favorable for the adsorption of Cr(VI),The difference of Cr(VI)adsorption between modified activated carbon and unmodified activated carbon was studied. It can provide a reference for the further study of Cr(VI)adsorption on activated carbon. Finally, the future research direction of activated carbon was put forward.
