Abstract
The invention aims to provide a formaldehyde adsorbent capable of modifying coal cinder through acid. In order to realize the purpose, the invention adopts the technical scheme as follows: fire coal cinder is smashed, a certain amount of cinder powder is taken, 20-50 ml of an acid modifier formed by mixing 1 mol/L sulfuric acid solution and 1 mol/L hydrochloric acid solution according to the volume ratio of 3:1 is added, after uniform stirring is performed, the mixture is put in a thermostatic waterbath oscillator with the temperate of 30-50 DEG C, and oscillated for 40-60 minutes, filtration is performed, distilled water is utilized to wash a filter cake to be neutral, the filter cake is put in an electrothermal air-blast drying oven, dried at 105 DEG C, and bottled for standby application, so that the formaldehyde adsorbent is obtained.
Description
Technical field
The present invention relates to formaldehyde absorbing field, be specifically related to a kind of formaldehyde adsorbent that cinder is carried out to sour modification.
Background technology
Formaldehyde (formaldehyde) is a kind of primary poisonous substance, is mainly to stimulate eye and respiratory mucosa on the impact of health, produces allergy, there is immunologic dysfunction, cause liver, injury of lungs, affect central nervous system, the inhereditary material in also can damaging cells.
Because formaldehyde synthetic has stronger cohesive, and can improve the hardness of sheet material and insect protected, antiseptic power, so formaldehyde is widely used among various building and ornament materials.
Absorption method is to process a kind of important physical chemistry method of harmful in waste water and waste gas and difficult degradation pollutant, and active carbon is the most frequently used sorbing material, but due to lack of material, cost is higher, regeneration is difficult etc., and reason is restricted its application.Taking industry and agricultural wastes as raw material, preparation and exploitation are cheap, to replace active carbon be the important directions that sorbing material is studied to efficient adsorption material.
Summary of the invention
The object of this invention is to provide a kind of formaldehyde adsorbent that cinder is carried out to sour modification, the lack of material existing to overcome prior art, the shortcoming that cost is high.For achieving the above object, the technical solution used in the present invention is as follows:
By broken coal furnace ground-slag, get a certain amount of pulverized slag, add 20-50ml acid modifier (1mol/L sulfuric acid and 1mol/L hydrochloric acid solution by volume 3:1 mix), stir and be placed on the 40-60min that vibrates in the water bath with thermostatic control oscillator of 30-50 DEG C, filter, with distilled water, Washing of Filter Cake is extremely neutral, put into 105 DEG C of oven dry of electric drying oven with forced convection, bottle for subsequent use, obtain this formaldehyde adsorbent.
There is following distinguishing feature in the present invention:
(1) invent described formaldehyde adsorbent, raw material sources are extensive, cheap;
(2) invent described formaldehyde adsorbent preparation method simple, adsorption rate is high;
(3) invent described formaldehyde adsorbent stable performance, the life-span is long, can preserve for a long time use.
detailed description of the invention:
