Method for catalytically degrading estrogen-like contaminant by simulating natural light

Abstract

The invention relates to a method for simulating natural photo-catalysis to degrade estrogen contaminant, which comprises adding catalyst into the water solution of estrogen contaminant of which the mass density is 10-3-10mg / L, and arranging the solution in an artificial climate chamber, keeping luminous intensity at 12000-15000Lux, using circulation radiation that radiates at 10-30Deg. C for 8-16h, keeps dark at 0-20Deg. C for 4-8h, and completing one circulation in 12-24h, at least processes one circulation. The catalyst is composed of A and B parts, wherein A part is bivalent ortrivalent soluble ferric salt, B part is the soluble salt of alkali metal, the mass ratio of the A and B parts is 0.01-1, and the mass ratio between the catalyst and estrogen is 0.01-1. The inventionhas warm reaction, low cost, high degrade rate, non secondary pollution, and wide application for degrading estrogen contaminant with wide distribution and low density, therefore, the invention has wide industrial application outlook.

Description

technical field The invention relates to a method for photodegradation and removal of estrogen pollutants, in particular to a method for catalyzing and degrading estrogen pollutants by abiotic factors under simulated natural light conditions. Background technique Environmental estrogen refers to a class of exogenous compounds that, after entering the body, interfere with the synthesis, release, operation, metabolism, and combination of substances normally secreted in the body, activate or inhibit the function of the endocrine system, thereby destroying it to maintain the stability of the body Sexual and regulatory substances. It interferes with many aspects of the human or animal endocrine system and causes abnormal effects. Environmental hormones are divided into natural estrogens, phytoestrogens and fungal estrogens, synthetic estrogens, and environmental chemical pollutants. The hazards of environmental estrogen mainly include: at extremely low concentrations, it can ...

AI Technical Summary

Problems solved by technology

The effect of biodegrading estrogen is better, but the pollutants must be collected, which is difficult to operate in practical applications

In addition, there are methods for degrading estrogen such as ozone oxidation, activated carbon adsorption, and ultraviolet light irradiation. These methods are not only costly, but also have poor effects.
