The invention discloses a kind of difunctional aqueous phase sorbing material with zwitterion eutectoid content characteristic, it is with triblock copolymer P123, tetraethoxysilance, aluminium isopropoxide as primary raw material, use direct synthesis technique by inorganic Al ion doping in matrix skeleton, produce cation activity adsorption site, then it is grafted large space steric hindrance organic group by rear grafting at its channel surfaces, produces anion active adsorption site.This sorbing material introduces two kinds of electrical contrary adsorption sites in same matrix, and utilize the space steric effect of organic group, the spontaneous complex fail successfully avoiding Acid and basic sites reacts, thus produce the molecular sieve adsorption material (Al SBA 15 G) with anions and canons adsorption site, the sewage system that zwitterion is coexisted by it has the purifying property of excellence, solve tradition sorbing material and can only adsorb single electrical ion, the problem that sewage adsorption treatment cost is high, has preferable application prospect. |
