Abstract

A method for preparing water-treatment activated alumina balls, which belongs to the field of environmental purification functional materials; the preparation method: 1) mixing ethanol, zinc acetate and aluminum isopropoxide in a flask, heating and keeping it warm, and then adding 15% four Butyl ammonium hydroxide ethanol solution, sodium acetate, tributyl phosphate, continue to heat and keep warm, evaporate the solution in the flask to the remaining 2 / 3 of the volume, and then prepare the aluminum-zinc mixed solution; 2) add activated alumina balls treated with phosphoric acid into the aluminum-zinc mixed solution, carry out hydrothermal reaction, filter the solid-liquid mixture after the reaction, and clean the solid matter; 3) dry the solid matter after cleaning, then calcinate at high temperature, and obtain water-treated activated alumina balls after cooling; The invention prepares an Al-Zn-O surface bonding coating on the surface of an activated alumina sphere, which can not only remove pollutants in water through adsorption, but also degrade the adsorbed organic pollutants through a photocatalytic reaction so as to have continuous adsorption capacity.

Description

technical field [0001] The invention belongs to the field of environmental purification functional materials, and in particular relates to a preparation method of water treatment activated alumina balls. Background technique [0002] Activated alumina balls are also known as water-purifying activated alumina, and the alumina used in catalysts is usually called activated alumina. It is a porous, highly dispersed solid material with a large surface area, and its microporous surface has the characteristics required for catalysis, such as adsorption performance, fluorine removal performance, drying performance, surface activity, and excellent thermal stability. properties, etc., so it is widely used as a household desiccant and a catalyst and catalyst carrier for chemical reactions. Modern water-purifying activated alumina is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength and strong hygroscopicity. In addition to being use...
