Problems solved by technology

Known indoor pollutants include formaldehyde, ammonia, benzene series, nitrogen oxides, carbon monoxide, etc. The adsorption of activated carbon alone is not enough, and the adsorption of activated carbon is saturated, which mainly acts as a "porter". The role of formula, can not fundamentally remove the pollution
For example, formaldehyde, the most serious formal

Abstract

The invention provides a preparation method of a medical stone purifying agent for adsorbing and decomposing formaldehyde, and the preparation method comprises the following steps of: (1) taking potassium permanganate and putting potassium permanganate into a container; adding de-ionized water and heating to 50-80 DEG C; agitating and dissolving to obtain a solution for further use, wherein the solution is a deep purple immersing solution and the concentration is 3-11%; (2) adding medicine stone grains into the prepared immersing solution, wherein the immersing modifying temperature is 40-60 DEG C; agitating for 1-2 hours; filtering and drying at 100-140 DEG C to obtain the medical stone purifying agent; and (3) putting the prepared medical stone purifying agent into a space needing to adsorb the formaldehyde, and after adsorbing the formaldehyde by the medical stone grains with more pores, oxidizing and decomposing to obtain pollution-free carbon dioxide and water desorption. According to the preparation method disclosed by the invention, a strong oxidant is used as an active component to be prepared into a solution; a medical stone carrier is subjected to oxidizing modification and the formaldehyde is oxidized and decomposed into the pollution-free carbon dioxide and the water desorption, and the effect on adsorbing and purifying the formaldehyde is very good.

Description

technical field [0001] The invention belongs to the field of environmental purification, and in particular relates to a preparation method of a medical stone purifying agent for adsorbing and decomposing formaldehyde. Background technique [0002] In daily life, formaldehyde is mixed in paints, various paints, fiberboards, plywood, etc. With home decoration, it is brought into the family and becomes a major killer of health. Free formaldehyde in the air will bring great irritation to the human body. , High concentrations of formaldehyde have a mutagenic effect on DNA, and are recognized by the World Health Organization as a chemical substance that is toxic and carcinogenic to the human body. [0003] At present, the common indoor air purification technologies mainly include adsorption, photocatalytic degradation, plasma technology, electrostatic technology, ozone treatment, and negative ion technology. Photocatalytic technology requires special catalysts, which are costly, ...
