摘要：

为研究稻秸秆纤维对Cu2+的吸附性能，测试了Cu2+初始质量浓度、处理时间、处理温度、固液比和pH值等因素对稻秸秆纤维吸附效果的影响，并对吸附前后的稻秸秆红外光谱进行了分析比较。实验结果表明：稻秸秆纤维对铜离子的吸附以物理吸附为主，也存在少量化学吸附；稻秸秆纤维对Cu2+具有快速、良好的吸附性能，尤其对低质量浓度的Cu2+溶液吸附效果较好；溶液的初始pH值对稻秸秆纤维吸附作用影响较大，环境温度对稻秸秆纤维吸附作用影响较小；当固液比值为7.5mg/L、溶液初始pH值为5时，稻秸秆对Cu2+的吸附性能达到最佳。

Abstract:

In order to study the adsorption properties of rice straw fiber for Cu2+,the influence of initial Cu2+ concentration, time,temperature, ratio of solid to liquid and pH value on adsorption were discussed.The infrared spectroscopy before and after adsorption were analyzed and compared.The results show that the adsorption properties of Cu2+ by rice straw fiber mainly is a physical adsorption. At the same time, a very small amount of chemical adsorption exists in the adsorption process. Rice straw fiber, for Cu2+, has fast and good adsorption properties, and has better adsorption effect especially for Cu2+ of low concentration; the influence of the initial pH value on adsorption properties of rice straw fiber is large, ambient temperature bas less effect on the adsorption properties of rice straw fibers; and when the solid-liquid ratio of 7.5mg/L, the initial pH value is 5, and the adsorption priperties of rice straw to Cu2+ reach the best.

Key words: rice-straw fiber, copperions, adsorption property, infrared spectroscopy
