Description
Technical field
The present invention relates to a kind of Environmental-protecting dust-removing filtering material and preparation method, particularly relate to a kind of high-performance adsorbent and
Its preparation method.
Background technology
Aluminium hydroxide adsorbent hygroscopicity is strong, and after water suction, the most swollen not splitting maintains the original state, and product is nontoxic, tasteless, odorless, insoluble
In water and organic solvent, it is to form through scientific allocation, catalysis polish with high-purity hydrogen aluminium oxide.It can serve as high-fluorine water
Defluorinating agent, makes a kind of molecular adsorbent with huge specific surface area.When the pH value of former water and basicity are relatively low, fluorine removal capacity is relatively
Height, more than 3.0mg/g.Can be used for drinking water and the fluorine removal of commercial plant, dearsenization, sewage decoloring, deodorization etc..
Aluminium hydroxide adsorbent has many capillary channels, and surface area is big, can make as adsorbent, desiccant and catalyst
With.Polarity power always according to adsorbent determines that water, oxide, acetic acid, alkali etc. are had stronger affinity simultaneously,
Active aluminium hydroxide is a kind of micro-water depth desiccant, is also the adsorbent of absorption polar molecule.
Under usual terms, aluminium hydroxide can not react with silicate, soap, and tradition utilizes solid phase mixing to prepare
Reaction uneven.
Summary of the invention
The purpose of the present invention is that and provides to solve the problems referred to above that a kind of adsorption rate is fast, have bigger absorption
Specific surface area, the high-performance adsorbent of absorption life-span length.
To achieve these goals, the present invention is achieved by the following technical solutions: a kind of high-performance adsorbent and
Preparation method, it comprises the following steps:
1) taking 200ml deionized water, regulation ph is 6-7；
2) heating deionized water is to 50-60 DEG C, is added in deionized water by 50-100g organo-aluminium and obtains reactive hydrogen aluminium hydroxide；
3) in above-mentioned activating agent, the silicate of 100-200g and the soap of 50-100g are added, at sonotrode
Under the conditions of sounding Cavitation, reaction 2-3h obtain containing soap, silicate and the reactive compound of hydrogen aluminium hydroxide；
4) above-mentioned active compounds solution is filtered, dry and finally obtain the present invention.
Further, a kind of high-performance adsorbent and preparation method thereof, the frequency of sonotrode in described step 3)
For 50-60KHz.
Particularly, a kind of high-performance adsorbent and preparation method thereof, in described step 3), silicate is magnesium silicate, silicic acid
One in aluminum, potassium silicate, sodium silicate；Described soap is the one in sodium soap, fatty acid potassium and fatty acid aluminium.
The method have the advantages that the high-performance adsorbent of the present invention avoids tradition and utilizes solid phase in sum
The situation of the reaction inequality being mixed with, its adsorption rate is fast, and has bigger adsorption specific surface area, and the absorption life-span is long.
