Study on the adsorption of phosphate in water by La-modified cellulose

Abstract In this experiment, cellulose microspheres were prepared by hydration at high temperature and impregnation with lanthanum chloride solution. The surface morphology and structural characteristics of the modified biomass were analyzed by SEM, XRD and IR. In addition, the adsorption capacity of La-modified cellulose to phosphate in water at different pH and initial concentration had been studied, and the acid condition was more favourable for phosphate removal.
