Abstract

A preparing method of a sodium bismuthate based visible light catalysis paper material is provided. The method includes 1) preparing sodium bismuthate, 2) preparing a plant fiber suspension, and 3) preparing the sodium bismuthate based visible light catalysis paper material. The sodium bismuthate that is a photocatalyst and has a visible light catalysis function is adopted as a base catalyst and is loaded on plant fibers. The plant fibers are a good catalyst carrier and can avoid agglomeration of sodium bismuthate nanometer particles, thus ensuring adsorption and catalytic activity. The methodis simple in process and convenient to operate, and efficient degradation and mineralization of organic pollutants can be achieved by utilizing strong adsorption and catalysis properties of the catalyst.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a preparation method of a sodium bismuthate-based visible light catalytic paper material. Background technique

[0002] my country is a country that lacks water resources, and the pollution of water resources is relatively serious, which makes water resources face a more severe situation. In industrial wastewater, organic pollutants are the main source of pollution and have a great impact on the water environment. Therefore, it is an urgent task to conduct advanced treatment of organic pollutants in industrial wastewater to achieve discharge standards and even reuse.

[0003] With the continuous development of water treatment technology, people have found that the use of oxidants, electricity, light, catalysts, etc. can effectively activate H 2 o 2 and O 2 And other green oxidants, thus generating extremely active free radicals in the reaction. When these free radica...
