| description | One embodiment of the present invention provides a method for producing a cellulose from chemical pulp by means of a treatment liquid that is composed of an aqueous solution containing a mineral acid and a peroxide, which is characterized by comprising at least the steps (a)-(c) described below, and which is also characterized in that a regenerated treatment liquid prepared in the step (c) is reused as a treatment liquid in the step (a). (a) a step for obtaining a cellulose by lowering the degree of polymerization of chemical pulp by means of hydrolysis using a treatment liquid that is composed of an aqueous solution containing a mineral acid and a peroxide (b) a step for separating the cellulose obtained in the step (a) and the used treatment liquid from each other (c) a step for preparing a regenerated treatment liquid by adding a mineral acid and/or a peroxide into the used treatment liquid, which has been separated in the step (b). |
