| Abstract: | To develop the approaches for sewerage treatment,a kind of novel cellulosic fiber modified by β-cyclodextrin was prepared.Its adsorption capability for heavy metal ions like copper(II) and organic dye like neutral red from aqueous solutions was also investigated by atomic absorption spectrometry and UV-vis spectroscopy.Results show that the adsorption capability of the novel cellulosic fiber to copper ion reaches 6.24 mg/g and the adsorption process fits for Langmiur model.Moreover,the novel cellulosic fiber can form inclusion complexes with neutral red.The novel fiber exhibits advantages of high adsorption for heavy metal ions and organic dyes,easy preparation and operation process,and pocesses good potential applications. |
