改性荷叶对水溶液中环丙沙星的动态吸附研究

Study on the Dynamic Adsorption of Ciprofloxacin in Aqueous Solution by Modified Lotus Leaf

用NaOH改性荷叶动态吸附水体中的环丙沙星。考察了改性荷叶床层高度、溶液流速和溶液浓度对改性荷叶吸附环丙沙星的影响,并利用Thomas模型对改性荷叶吸附环丙沙星的数据进行拟合,确定了柱吸附的特征参数。结果表明:高床层和低流速有利于吸附的进行,Thomas模型可以较好地描述改性荷叶对环丙沙星的吸附。

Lotus leaf modified by Sodium hydroxidewas used to adsorb the Ciprofloxacin in water. The effect of the main operating conditions,suchasbed height,flow rate and concentrationon the adsorption was investigated by dynamic adsorption experiment.Andthe Thomas models was applied to determine the characteristic parameters of the column adsorption. The results show that high bed and low flow velocity were favorable for theadsorption. The model was found to be suitable to describe the dynamic behavior of ciprofloxacin adsorbed onto the modified lotus leaf.
