新型淀粉基微球对Ni^2＋的吸附行为及机理研究

摘要

The adsorption behavior of Ni^2＋ by new starch - based microspheres which were used as a carrier were investigated. It＇s adsorption behavior were characterized by FT - IR spectroscopy and X - ray diffraction（XRD）. The resuhs showed that starch -based microspheres （S- M） on Ni^2＋adsorption isotherms corresponded with both the Langmuir and Freundlich isotherm. The adsorption reaction was a spontaneous exothermic process.%以新型淀粉基微球为吸附载体，研究了微球对Ni^2＋的吸附性能，通过红外、X射线衍射仪对微球及其吸附产物进行表征。结果表明：淀粉基微球对Ni^2＋吸附等温线同时符合兰格缪尔和弗兰德里希等温方程；淀粉基微球对Ni^2＋的吸附为物理吸附过程。
