摘　　要：本文以不同方式干燥的香蕉皮为吸附材料,对重金属六价铬(Cr^(6+))进行吸附研究,分别从温度、pH、吸附时间、初始浓度、吸附剂的使用量等因素来探讨对六价铬吸附的影响。结果表明,六价铬离子最佳浓度为20μg/m L、最佳投料量为0.200 g、最佳pH为4、最佳吸附温度为45℃、最佳吸附时间为55 min,在此条件下,吸附性能冷冻-普通香蕉皮>非冷冻普通干燥香蕉皮>冷冻干燥香蕉皮。This article is based on different ways of drying banana peel as adsorption material. Then the heavy metal hexavalent chromium（Cr^（6＋）） was studied by means of adsorption, respectively from the temperature, p H value, adsorption time, initial concentration and adsorbent factors such as the use of to explore the influence of the adsorption of hexavalent chromium. The results show that the optimal concentration of hexavalent chromium as 20 mu g/m L, best inventory is 0.2 g, the best pH is 4, optimal adsorption temperature 45 ℃, the best time for 55 min. In this condition, the adsorption performance of frozen-common banana peel not frozen average dry banana peel freeze-dried banana skin.
