摘要: 通过改变投加量、pH、Cu(Ⅱ)浓度、吸附时长和温度等因素,研究灵芝菌糠对水中重金属Cu(Ⅱ)的吸附性能。结果表明,灵芝菌糠对水中重金属Cu(Ⅱ)具有较好的吸附性能,具有用于实际处理含Cu(Ⅱ)废水的应用前景。灵芝菌糠对Cu(Ⅱ)吸附的最佳条件是投加量30 g/L、pH=6、吸附时长90 min、温度35 ℃。吸附过程较符合Langmuir等温吸附模型。

Abstract: Ganoderma lucidum bran was used as the adsorption material, by changing the factors such as the dosage of bran, pH value, Cu(Ⅱ) concentration, adsorption time and temperature, the adsorption of Cu(Ⅱ) was studied. The results showed that Ganoderma lucidum bran had a good adsorption property for Cu(Ⅱ) in water, and it could be used in practical treatment of wastewater containing Cu(Ⅱ). The best conditions for the adsorption of Ganoderma lucidum bran to Cu(Ⅱ) were the dosage of 30 g/L, pH=6, adsorption time of 90 min, and temperature of 35 ℃. The adsorption process accorded with Langmuir isothermal adsorption model.

Key words: Ganoderma lucidum bran, Cu(Ⅱ) wastewater, adsorption performance, isothermal adsorption model
