Abstract

Abstract: In order to investigate the adsorption performance of Sanxan gel ball on methylene blue dye, this study prepared 0.6% hydrogel beads using Sanxan gel ball as the main research material, and after its vacuum freeze-drying, explored the adsorption of methylene blue through a variety of single factor experimental. The adsorption properties of Sanxan gel ball for methylene blue and the optimization of methylene blue adsorption conditions were studied. The results showed that the optimal conditions were as follows: when the initial adsorption concentration was 400 mg/L, the adsorption time was 12 h, the adsorption pH was 11, and the adsorption temperature was 25 ℃, the maximum adsorption capacity was 218.7 mg/g, and the removal rate was 95.2%. The methylene blue adsorption process of Sanxan gum conforms to the first-order kinetic adsorption model. This research provides a new material for adsorbing methylene blue dyes, which can effectively reduce pollution.
