The adsorption of urea nitrogen onto chitosan coated dialdehyde cellulose (CDAC) under urease catalysis was studied in a batch system. The equilibrium isotherm of urea nitrogen adsorption onto CDACs with different degree of oxidation (DO) and the kinetics of adsorption with respect to the DO of CDAC (41, 60 and 74%), the initial urea nitrogen concentration (544, 635 and 785mgL −1 ), temperature...
