A method for controlling the catalytic oxidation of cellulose comprises: - using a heterocyclic nitroxyl compound as catalyst， - oxidizing cellulose in a reaction mixture comprising liquid medium， the catalyst and hypochlorite as main oxidant， - analyzing one or more oxidative chlorine species dependent on the hypochlorite concentration of the reaction mixture on line in the reaction mixture or in a gas composition which is in contact with the reaction mixture， and - controlling supply of hypochlorite to the reaction mixture on the basis of the analysis.
