Preparation method for solid catalyst for ozone heterogeneous oxidization

Abstract

The invention relates to a preparation method of a solid catalyst for ozone heterogeneous oxidation, which belongs to the technical fields of environmental protection and chemical catalysts. The preparation method is to use activated carbon, carnallite, potassium feldspar, boronite, magnesium spinel and peridotite porous mineral material as a carrier, and after the carrier is modified by lithium hypochlorite and bis(acetylacetonate) beryllium to expand pores, The surface active agent dimethyl hexadecylethyl ammonium ethyl sulfate is added to carry out surface activation treatment under the action of ultrasonic waves, and then the composite mineralizer composed of borax and potassium sulfate formed by the ultrasonic surface activation carrier in a hydrothermal reaction kettle, acetyl Samarium acetone, tris(4,4,4‑trifluoro‑1‑(2‑thiophene)‑1,3‑butanedione) europium, tris(6,6,7,7,8,8,8‑heptafluoro ‑2,2‑Dimethyl‑3,5‑Octenedione) Dysprosium(III), Thulium(III) Trifluoromethanesulfonate Rare Earth Metal Compounds Catalytic Active Auxiliary, Cobalt Gluconate, Molybdenum L‑Aspartic Acid , catechol ethylenediamine tungsten complex, hexachloroosmium dipotassium transition metal catalytic active center component, under the action of emulsifier octadecyl dimethyl hydroxyethyl ammonium perchlorate for hydrothermal reaction, the reaction After the product is dried to remove moisture, it is burned in a muffle furnace at a certain temperature to obtain a solid catalyst for ozone heterogeneous oxidation.

Description

technical field [0001] The invention relates to a preparation method of a solid catalyst for ozone heterogeneous oxidation, which belongs to the technical fields of environmental protection and chemical catalysts. Background technique [0002] Ozone oxidation technology utilizes the strong oxidation ability of ozone, which can oxidize and decompose many organic pollutants, and is widely used in wastewater treatment. Ozone catalytic oxidation technology is divided into ozone homogeneous catalytic oxidation and ozone heterogeneous catalytic oxidation. Ozone homogeneous catalytic oxidation has catalysts that are difficult to separate, recycle and reuse, and the low utilization rate of ozone leads to high water treatment operation costs. Ozone heterogeneous catalytic oxidation technology has the advantages of easy separation and recovery of catalysts and reusable use, high ozone utilization rate, and high removal rate of organic pollutants, which reduces water treatment. The ad...

Problems solved by technology

Due to the wide variety of pollutants and the complex chemical composition of wastewater, it will have adverse effects on the performance of the catalyst, such as adsorption and anti-toxicity, and the catalyst will easily lose its catalytic activity.

At present, the main problems of the preparation method of ozone heterogeneous oxidation solid catalyst are small adsorption capacity, low adsorption selectivity, poor toxicity resistance of the catalyst, and easy
