S21. deionized water is slowly added in dehydrated alcohol, wherein the molar ratio of dehydrated alcohol and deionized water is 1:
0.15-0.20；And nitric acid is added and adjusts PH to 2-3, solution B is made；
S22. in the case where being vigorously stirred, solution B is added dropwise in solution A, guarantees that solution A does not generate muddiness,
Form colloidal sol C；
S23. the colloidal sol C that step S22 is obtained is dried into 8h under the conditions of 100 DEG C；
S24. product grind into powder step S24 dried is placed at 500-650 DEG C calcining and forms titanium dioxide and receives
Rice flour end.
Further, the method that titanium dioxide is impregnated in low-order coal are as follows: titanium dioxide is dissolved in deionized water, solution is dense
Degree is 0.5%, and immerses low-order coal, and the mass ratio of low-order coal and titanium dioxide is 3:1.
Further, the dipping, stir process time are 0.5~2h.
Further, mixing speed is 500r/min during the stirring impregnation.
Further, the temperature of the drying process is 100 DEG C, drying time 6h.
A kind of coal adsorbing material that the preparation method of complex coal adsorbing material is prepared.
Compared with prior art, the beneficial effects of the present invention are:
1) will obtain NEW TYPE OF COMPOSITE coal adsorbing material using dipping method on titanium dichloride load to low-order coal, prepare
Simple process, it is easy to operate；
2) the complex coal adsorbing material of preparation is provided simultaneously with the characteristics of light-catalyzed reaction removal pollutant of photochemical catalyst
And the adsorption function of low-order coal, adsorption capacity is strong, and can realize that the original position of low-order coal is quick again under the action of natural light
Raw, reuse stability is good, nontoxic, without secondary pollution to environment；
3) coal adsorbing material can be applied to handle substance containing bio-toxicity, organic pollutant difficult to degrade and be rich in
The water body that nutrient, heavy metal etc. need to purify realizes the circular regeneration of adsorbent material using titanium dioxide, without frequently replacement
Adsorbent reaches the good result that continuing purge repairs city appearance water body.
