Embodiment 1

[0032] The preparation method of photocatalyst coated activated carbon material is carried out according to the following steps:

[0033] 1) Soak high-quality activated carbon particles with a particle radius of 2-20nm in a nonpolar ionized water photocatalyst solution (the particle radius of the photocatalyst is 8-10nm) for 24h;

[0034] 2) During the soaking process, the temperature of the solution is controlled between 15-20°C, and the mass percentage concentration of the photocatalyst solution is between 20-30%. After soaking for 24 hours, drain the activated carbon and let it dry naturally for 24 hours for preliminary crystallization. combine;

[0035] 3) Then put it into a drying oven at a constant temperature of 100°C and dry for 8-10 hours for further crystallization, chelation, and solidification.

Embodiment 2

[0037] The preparation method of photocatalyst-coated zeolite material is carried out according to the following steps:

[0038] 1) Soak high-quality zeolite particles with a particle radius of 5-10nm in a nonpolar ionic water nano-titanium dioxide solution (the particle radius of nano-titanium dioxide is 5-6nm) for 26h;

Abstract

The invention provides a photocatalyst coated carrier material which is prepared from carrier particles and photocatalyst solution with mass percentage concentration of 20% or more. A preparation method includes the steps: (A) soaking the carrier particles in the photocatalyst solution for 24 hours or more, draining the soaked carrier particles, and naturally air-drying the drained carrier particles; (B) drying the carrier particles at the temperature of 100 DEG C or more to obtain the photocatalyst coated carrier material. According to the photocatalyst coated carrier material, the photocatalysts are coated on the carrier particles, environmental hormone hazardous substances such as formaldehyde, benzene and bisphenol A are adsorbed, further photo-catalysis of the photocatalysts is implemented, so that hazardous substances can be decomposed into harmless water and carbon dioxide, the environments are protected, pollutants are degraded, and the carrier material solves the problem thata carrier substance such as a single activated carbon can only simply adsorb hazardous substances in a tradition method, and the hazardous substances cannot be completely treated.

Description

technical field [0001] The invention relates to the processing field of novel environmental protection adsorption materials, in particular to a photocatalyst-coated film carrier material and its preparation method and application. Background technique [0002] The so-called environmental hormones refer to chemical substances that exogenously interfere with the secretion of biological substances. These substances can simulate natural hormones in the body, bind to hormone receptors, affect the amount of hormones in the body, and cause the body to produce excessive accumulation of hormones in the body The role of the endocrine system disorders. In turn, it hinders normal reproduction, development and other functions, and even causes malignant tumors and biological extinction. The reason for the appearance of environmental hormones is that, firstly, there is a large amount of environmental hormones in food and drinking water, which is causing the decrease of men's sperm, male d...
