Preparation of β-cyclodextrin/chitosan Membranes and Its Application in the Wastewater Treatment of Acid Dyes

In this study a new and environmental biopolymer membrane has been synthesized by incorporating beta-cyclodextrin polymers as the reagent and using vinyltriethoxysilane(JH-V151) as crosslinking agent. The FT-TR and SEM were used to characterize the functional groups, morphology and pore-size. The results indicated that the prepared membranes exhibited relatively large pores, and the average pore size was 5 mu m. The study of adsorption behavior demonstrated that the prepared membranes could be considered as an efficient adsorbent for the removal of acid dyes from the wastewater.
