Preparation of Cotton Fiber Based Adsorbent and Its Adsorption Performance for Metal Ions

2021年8月26日

Abstract: In this paper, a new type of cotton fiber based adsorbent is prepared by selectively oxidizing cotton fiber, and then grafting the HBP—OH and β-cyclodextrin. Studies on the adsorption of heavy metal ions (Pb2+, Cd2+, Cu2+) showed that the prepared cotton fiber based adsorbent had a higher adsorption capacity than the raw cotton fiber. Its adsorption capacity is 12-20 times that of raw cotton fiber.


Key words: cotton fiber; β-cyclodextrin; HBP—OH; heavy metal
