Abstract
The invention discloses a preparation method for a bamboo pulp cellulose-based integrated Fenton catalyst Fe<3+>C2O4/R. The preparation method is characterized in that tri-valent iron and oxalic acid are subjected to coordination to form a complex Fe<3+>C2O4, and the complex Fe<3+>C2O4 is loaded on bamboo pulp cellulose-based porous resin R synthesized by bamboo pulp to form the integrated Fenton catalyst Fe<3+>C2O4/R; under visible light, hydrogen peroxide can be catalyzed in an acceleration manner to degrade dye type organic pollutants in printing and dyeing wastewater. A product prepared by the method is high in efficiency, environment-friendly and low in cost; the problems of secondary pollution, high oxidization cost, low degrading efficiency and the like which are caused by a fact that the Fenton reagent cannot be repeatedly used in the conventional dye type organic pollutant Fenton oxidization degrading are solved, and the creation concept of using bamboo resources in China in a high value is provided, and thus the preparation method has obvious environmental and social significance.
