Embodiment Construction

[0022] The invention is further illustrated by the following examples.

[0023] A) Preparation of crosslinked macroporous polystyrene-divinylbenzene copolymer (white ball)

[0024]In a three-necked flask, add 1200ml of 1% gelatin aqueous solution and an oil phase composed of 176.0g of styrene, 14.0g of divinylbenzene, 2.0g of benzoyl peroxide and 100.0g of liquid wax. Adjust the stirring speed to a suitable particle size, and raise the temperature to 80°C for 12 hours. Then cool for 2h, filter, and wash the polymer with hot water. Then extract with acetone for 8 hours, and finally vacuum-dry for 2 hours at a temperature of 60°C and a vacuum degree of 1333pa to obtain white balls.

[0025] 2. Chloromethylation of cross-linked macroporous polystyrene-divinylbenzene (chlorine balls)

[0026] In a 2000ml three-neck flask, add 200.0g white balls, use 1200ml chloromethyl ether to swell, then add 60.0g catalyst in batches, stir, and react at a temperature of 311K for 12h. After c...

Abstract

The invention relates to a method for ornamenting FePcS on a crosslinking ball of polystyrene divinyl benzene (abbreviated for a chlorine ball) after being processed through chloromethylate. The FePcS accounts for 0.6-4.5 percent in the whole catalyst in percentage by weight. The catalyst can utilize visible light to activate H2O2 so as to catalyze and degrade waste water produced by organic pollutants such as dye, and the like, wherein the decolorizing rate can reach 100 percent; the chemical oxygen demand (COD) removal rate is more than 93 percent; and the total organic carbon (TOC) removal rate reaches more than 78 percent. The FePcS is loaded on resin, can improve the antioxidant capacity of phthalocyanine and is convenient for recycling, thereby reducing the cost and avoiding secondary pollution.

Description

technical field [0001] The invention relates to a photocatalyst and a preparation method thereof, in particular to a resin catalyst capable of catalytically degrading organic pollutants by utilizing visible light and a preparation method thereof. technical background [0002] In recent years, advanced oxidation techniques (AOTs) using hydroxyl radicals (·OH) to degrade and mineralize organic wastewater have attracted the attention of environmental workers. However, in the past two decades, a lot of attention has been focused on the photocatalytic degradation of organic pollutants using ultraviolet light. However, there are some limitations in using ultraviolet light, such as large power consumption, high price, etc. Only about 4% UV light. Therefore, it is of great significance for environmental protection and energy saving to try to use cheap and low-cost visible light to treat environmental pollutants or directly use sunlight to treat wastewater. [0003] The heterogeneo...
