Embodiment 1

[0030] 1) Coke pretreatment: Crush large pieces of coke and select coke with a particle size of 5-7 mm; wash with distilled water several times until the upper liquid has no black floating powder; dry in a far-infrared rapid constant temperature drying oven at 403 K for 2 h to constant weight.

[0031] 2) Modification of coke

[0032] Weigh an appropriate amount of pretreated coke into a beaker, soak it in 20% NaOH for 36 h (the liquid level is above the coke, seal it, and store it in the dark at room temperature); after 36 h, wash it with ultrasonic water. Firstly, the alkali-soaked coke was ultrasonically washed twice with a solution of water and ethanol with a volume ratio of 1:1, and then washed with deionized water for 5-6 times (stirring while washing with water during the ultrasonic washing process), and the washing time for each time was 7 min until the upper liquid is not cloudy. After ultrasonic washing, the coke was dried in a far-infrared rapid constant temperatu...

Embodiment 2

[0039] 1) Pretreatment of coke: crush large pieces of coke and select coke with a particle size of 5-7 mm; use distilled water to wash several times until the upper liquid has no black floating powder; Heavy.

[0040] 2) Modification of coke

[0041]Weigh an appropriate amount of pretreated coke into a beaker, soak it in 20% NaOH for 30 h (the liquid level is above the coke, seal it, and store it in the dark at room temperature); after 30 h, wash it with ultrasonic water. First, the alkali-soaked coke was ultrasonically washed 3 times with a solution of water and ethanol with a volume ratio of 1:1, and then washed 5-6 times with deionized water (stirring while washing with water during the ultrasonic washing process), and the cleaning time for each time was 7 min until the upper liquid is not cloudy. After ultrasonic washing, the coke was dried in a far-infrared rapid constant temperature drying oven at 400 K for 2 h to obtain alkali-modified coke.

[0048] 1) Pretreatment of coke: crush large pieces of coke and select coke with a particle size of 5-7 mm; use distilled water to wash several times until the upper liquid has no black floating powder; Heavy.

[0049] 2) Modification of coke

[0050] Weigh an appropriate amount of pretreated coke into a beaker, soak it in 20% NaOH prepared for 40 h (the liquid level is above the coke, seal it, and store it in the dark at room temperature); after 40 h, wash it with ultrasonic water. First, the alkali-soaked coke was ultrasonically washed 3 times with a solution of water and ethanol with a volume ratio of 1:1, and then washed 5-6 times with deionized water (stirring while washing with water during the ultrasonic washing process), and the cleaning time for each time was 7 min until the upper liquid is not cloudy.

Abstract

The invention relates to the technical field of wastewater organic matter treatment, in particular to a method for catalytically removing bisphenol A by using Ce-doped BiOCl-loaded coke. The method includes preparing a Ce-doped BiOCl-loaded catalyst through coke pretreatment, modification, impregnation, loading and drying in sequence; adding the catalyst into bisphenol A-containing wastewater andperforming illumination removal; wherein the molar ratio of Ce to BiOCl in the catalyst is 0.00087; the BiOCl is doped with the rare earth element Ce and is loaded on the coke by exerting the microstructure of the coke, so that the removal rate of the bisphenol A in the wastewater is remarkably improved; Ce is doped, so that the activity of a photo-induced electron hole (e<->-h<+>) pair is improved, the removal rate of the catalyst on bisphenol A reaches 100%, and meanwhile, the removal time is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of waste water organic matter treatment, in particular to a degradation catalyst, in particular to a method for catalytically removing bisphenol A supported by coke with Ce-doped BiOCl. Background technique [0002] With the development of modern industry, people's demand for chemical products is also increasing, and more and more organic pollutants are discharged into the soil and water, which poses a great threat to the homeland on which human beings depend for survival. Studies have shown that my country's environmental pollution has deteriorated from point source pollution in the 1970s to large-scale regional pollution. Therefore, it is particularly important to seek an efficient and pollution-free catalyst for the degradation of organic matter. The degradation methods currently studied mainly include: physical degradation, chemical degradation, and biological degradation. Due to the advantages of low ...
