摘要:

采用本实验室自制的羊骨基活性炭,研究其在不同吸附时间、不同溶液初始浓度、不同投加量、溶液不同的pH值条件下对Pb() 的吸附规律。结果表明:当Pb)溶液的初始浓度为80 mg/L、活性炭投加量为0.10 g、吸附时间为6 h、溶液温度为45 时,羊骨基活性炭对Pb)的去除率高达99%。利用Langmuir吸附等温模型和Freundlich吸附等温模型对其吸附性能的表征得出:羊骨基活性炭对溶液中Pb)的吸附行为符合Langmuir吸附等温模型和Freundlich吸附等温模型,并且吸附等温曲线在Brunauer五种类型的等温吸附线中比较符合多分子层吸附等温线。

Abstract:

Activated carbon derived from sheep bones was preparedits adsorption for PbIIwas investigated by varying adsorption timeinitial concentrationactivated carbon dosage and pH value. The adsorption was found to follow Langmuir isotherm & Freundlich isotherm equations. Results showed that the Pb() removal ratio from solution by activated carbon from sheep bones was over 99% when the initial Pb() concentration was 80mg/L with 0.10g activated carbon dosage at 45 and adsorption time for 6 h. The adsorption isotherm curve partly accorded with the type multilayer isotherm in Brunauer 5 type isotherm equations.
