摘要
Abstract Cellulose is abundant in nature, and it has good biocompatibility and biodegradability. However, it has shortcomings such as insufficient ductility, poor solubility, and difficult in forming, which limits its further application in many fields, such as food and medicine. Cellulose/chitosan composite microspheres were prepared using carboxymethyl cellulose and chitosan as raw materials, anhydrous ethanol, and distilled water as coagulants by the crosslinking method. Fourier infrared spectroscopy (FT-IR), specific surface area and aperture test (BET), and scanning electron microscopy (SEM) were used to characterize the adsorption properties. The results showed that the adsorption rate of cellulose/chitosan was higher than that of a single substance. The maximum adsorption capacity of the cellulose/chitosan composite microsphere was 57.63 mg/g when the equilibrium was reached. Compared with single cellulose and chitosan, cellulose/chitosan composite microspheres had a better adsorption effect on Congo red. As a potential adsorption material, this material has shown good application value in the field of sewage treatment.
