Abstract：A series of chitosan-based boron nitride materials (BN-CSx, x=0, 20, 40) were prepared by using boric acid as the boron source and urea and chitosan as the double nitrogen sources by high-temperature calcination method. The structures of BN-CSx were analyzed by SEM, XRD, FT-IR and other characterization methods. Using dibenzothiophene (DBT) as the sulfide model, the adsorption performance of BN-CSx on DBT was compared and investigated. The results show that BN-CS20 had the best adsorption ability for DBT, and the adsorption capacity was up to 25.22 mg S/g. The results of kinetics, isotherm and thermodynamics experiments proved that the adsorption process of BN-CS20 on DBT coincided with the pseudo-second-order and Freundlich isotherm models, and room temperature was favorable to the adsorption.
