Embodiment 1
[0057] A magnetically ordered mesoporous Fe 3 o 4 The preparation method of @MCM-48 composite adsorption material, the specific steps are as follows:
[0058] S1, take 0.1g ferrite Fe 3 o 4 Dissolve in the chloroform of 3ml, 400W ultrasonic 15min, obtain mixed solution; What adopt here is Fe 3 o 4 nanoparticles;
[0059] S2, take half the volume of the mixed solution obtained in S1 and add it to 25ml of 0.8g / 100ml cetyltrimethylammonium bromide (CTAB) aqueous solution (that is, add 0.0005molCTAB), continue 400W ultrasonic stirring for 5min, and The temperature of the solution was raised to 60°C, and then continued to evaporate for 2 minutes to remove the organic chloroform. At this time, a surfactant-stabilized ferrite particle solution was obtained, and the ferrite particles showed hydrophilicity;
[0060] S3, take the ferrite particle solution obtained in S2 and add it to 62g of cetyltrimethylammonium bromide-ethylene glycol-water solution, stir for 10min; then add amm...
Embodiment 2
[0064] A magnetically ordered mesoporous Fe 3 o 4 The preparation method of @MCM-48 composite adsorption material, the specific steps are the same as in Example 1, the difference is only in the Fe used in S1 3 o 4 The mass is 0.2g.
Embodiment 3
[0066] A magnetically ordered mesoporous Fe 3 o 4 The preparation method of @MCM-48 composite adsorption material, the specific steps are the same as in Example 1, the difference is only in the Fe used in S1 3 o 4 The mass is 0.3g.
