Problems solved by technology
The main indicators for judging the adsorption function include adsorption rate and adsorption capacity. The activated carbon in the prior art has a good adsorption effect on BPA, the adsorption rate is fast (equilibrium time<2d), and the saturated adsorption capacity is relatively large (42~772mg / g), but activated carbon also has certain defects, which means that its adsorption capacity is difficult to exert if it is separated from its surface, so the development of new and efficient adsorption materials has become a problem that needs to be solved

Abstract
The invention discloses a preparation method of MIL-101 for adsorbing BPA in water and a derivative material of the MIL-101. The preparation method comprises the steps: firstly, putting a certain amount of Cr(NO3)3.9H2O and terephthalic acid into deionized water at the same time; placing the mixed solution in a reaction kettle to obtain a dark blue solution with the pH value of 2.58, placing the dark blue solution in a high-temperature environment of 218 DEG C for reaction, and cooling to obtain a suspension with the pH value of 0.5; separating a MOF solid by adopting a centrifugal machine, and washing by virtue of water, methanol and acetone; and then placing the washed solid in 20 mL of N,N-dimethylformamide for ultrasonic treatment, and after ultrasonic treatment is completed, placing the solid in a drying oven for drying to finally obtain dark green powder MIL-101. The preparation method is simple and efficient, and the obtained MIL-101 and the derivative material thereof can effectively adsorb the BPA component in water and meet various adsorption requirements.
Description
technical field [0001] The invention relates to the technical field of BPA treatment, in particular to a preparation method of MIL-101 and its derivative materials for adsorbing BPA in water. Background technique [0002] At present, the speed of industrial development is accelerating, and the environment is also being damaged more and more seriously. Water pollution control is facing very serious challenges. Bisphenol A (BPA) is an indispensable raw material in industrial production. It is widely used in the production of polycarbonate plastics and other products. It is harmful to the environment and has a negative impact on the endocrine of the human body. With the continuous increase of BPA emissions in the environment, the natural environment around industrial production is seriously polluted. If the human body lives in such an environment for a long time, the health of the body will be seriously affected. Therefore, experts and scholars in related fields at home and ab...
