采用静态吸附法研究花生、水稻和大豆秸秆对模拟Cu2＋废水的吸附效果,考察了吸附时间、固液比、pH值、初始Cu2＋浓度、秸秆粒径和溶液温度对Cu2＋的吸附量和去除率的影响,并用Henry、Freundlich、Langmuir等温方程拟合。结果发现,秸秆对Cu2＋的吸附主要受吸附时间、固液比、pH值的影响;Langmuir等温模式能更好地模拟秸秆对Cu2＋的吸附效果。
採用靜態吸附法研究花生、水稻和大豆秸稈對模擬Cu2＋廢水的吸附效果,攷察瞭吸附時間、固液比、pH值、初始Cu2＋濃度、秸稈粒徑和溶液溫度對Cu2＋的吸附量和去除率的影響,併用Henry、Freundlich、Langmuir等溫方程擬閤。結果髮現,秸稈對Cu2＋的吸附主要受吸附時間、固液比、pH值的影響;Langmuir等溫模式能更好地模擬秸稈對Cu2＋的吸附效果。

Adsorption of Cu2＋ from wastewater on peanut,rice and soybean straw was investigated using static adsorption method.The adsorption was studied by considering the effects of various parameters on the adsorption capacity of Cu2＋,such as adsorption time,solid-liquid ratio,pH,initial concentration of Cu2＋,particle size,and temperature.The results showed that the adsorption of Cu2＋ were mainly affected by adsorption time,solid-liquid ratio,and pH.Langmuir isotherm model can better describe the adsorption characteristics of Cu2＋.
