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
The invention belongs to depollution of environment field, relate in particular to a kind of preparation method of medical stone cleanser of adsorption-decomposition function formaldehyde.
Background technology
In daily life, formaldehyde is unworthily moved in coating, various paint, fiberboard, glued board etc., along with home decoration, bring family into, become a healthy large killer, formaldehyde free in the air can bring great excitant to human body, and the formaldehyde of high concentration has mutagenic effect to DNA, is regarded as the chemical substance toxic, carcinogenic to human body by the World Health Organization.
Common Techniques for Indoor Air Purification mainly contains absorption, photocatalytic degradation, plasma technology, electrostatic technique, ozone treatment, anion technology etc. at present.Photocatalysis technology need to have special catalyst, and cost is very high, and for ultraviolet ray strong dependence is arranged, and catalyst quantum productive rate is low, and is slow for the pollutant processing speed of indoor low concentration, is difficult to satisfy daily need; Although plasma technology can make it be decomposed into carbon dioxide and water the effect of organic exhaust gas process electric field, but carbon monoxide can occur with the side reaction of ozone, cause new pollution, and equipment be valuable in reaction, power consumption is high, and is not good to the pollutant treatment effect of low concentration; Electrostatic technique is only processed dust good effect; The character of ozone itself has determined that it is not suitable in indoor application; Anion technology can be so that room air becomes pure and fresh on sense organ, but helpless for contaminant gases.
Indoor air purification is most widely used at present is exactly active carbon, and it is a kind of absorption purifier of wide spectrum, and multiple air pollutants, bacterium, dust are all had absorption purifying effect.Known indoor pollutant has formaldehyde, ammonia, benzene homologues, oxynitrides, carbon monoxide etc., the suction-operated that only depends on active carbon is inadequate, and the absorption of active carbon has saturated phenomenon, mainly plays a kind of " porter " formula, can't fundamentally separate depollution.Such as formaldehyde the most serious in the indoor pollution, because its molecule is little and carbonyl is acid, and active carbon is owing to lack basic group so that the adsorption of PARA FORMALDEHYDE PRILLS(91,95) is very low.In recent years, activated alumina and relevant modified product thereof are widely used processing successful on the formaldehyde, and shortcoming is high expensive.
Summary of the invention
The present invention provides a kind of preparation method of medical stone cleanser of adsorption-decomposition function formaldehyde in order to address the above problem.
Technical scheme of the present invention is achieved in that a kind of preparation method of medical stone cleanser of adsorption-decomposition function formaldehyde, may further comprise the steps:
(1), get potassium permanganate in container, add deionized water, be heated to 50-80 ℃, stir and make its dissolving, solution is the maceration extract of darkviolet, concentration is 3-11%, and is for subsequent use;
(2), medical stone granule: is added in the maceration extract prepare, the dipping modification temperature is 40-60 ℃, stirs 1-2 hour, filters afterwards and dries under 100-140 ℃ temperature, namely gets the medical stone cleanser;
(3), the medical stone cleanser for preparing is put into the space that needs absorbing formaldehyde, after the medical stone granule: PARA FORMALDEHYDE PRILLS(91,95) of hole prosperity adsorbs, be free of contamination carbon dioxide and water desorption through peroxide decomposition;
A kind of preparation method of medical stone cleanser of adsorption-decomposition function formaldehyde may further comprise the steps:
(1), get potassium permanganate in container, add deionized water, be heated to 65 ℃, stir and make its dissolving, solution is the maceration extract of darkviolet, concentration is 8%, and is for subsequent use;
(2), medical stone granule: is added in the maceration extract prepare, the dipping modification temperature is 50 ℃, stirs 1.5 hours, filters afterwards and dries under 120 ℃ temperature, namely gets the medical stone cleanser;
(3), the medical stone cleanser for preparing is put into the space that needs absorbing formaldehyde, after the medical stone granule: PARA FORMALDEHYDE PRILLS(91,95) of hole prosperity adsorbs, be free of contamination carbon dioxide and water desorption through peroxide decomposition.
The invention has the beneficial effects as follows: preparation method of the present invention, adopt strong oxidizer as active component, after it is mixed with solution the medical stone carrier is carried out oxidation modification, the oxidation of formaldehyde that medical stone can be adsorbed after active constituent loading is finished is decomposed into free of contamination carbon dioxide and water desorption, the formation circulation absorption decomposes, enlarge adsorption capacity, following to purify for the absorption of formaldehyde has extraordinary effect.
