铜离子和六价铬离子在聚苯胺／凹凸棒石纳米复合材料上的竞争吸附
Rival Adsorption of Cu（II） and Cr（VI） Ions on Polyaniline/Attapulgite Nanocomposites
摘要
Abstract
A nanocomposite material of polyaniline/attapulgite doped by hydrochloric acid was prepared by in-situ polymerization. The adsorptive property for Cr（VI） and Cu（II ） in water was investigated. The main factors of impacting the adsorption rate, thermodynamic properties and adsorption isotherms of Cr（VI） and Cu（II） on the nanocomposite were analyzed. Moreover, the adsorption mechanism of the nanocomposite material on the dual ions was discussed via desorption. The results show that the adsorptive property on the composite materials on Cr（VI） is obviously better than that on Cu（ II ）, and the adsorption of Cr（VI） on the nanocomposite is mainly due to the chemisorption of PANI, however, the adsorption of Cu（II） on the nanocomposite mainly contributes to the ion exchange and chemisorption of ATP. The varying adsorption rates of Cr（VI） and Cu（II） depend on the different adsorption mechanisms on the nanocomposite material.关键词
