The invention discloses a preparation method of porous geological
polymer microspheres. The porous geological
polymer microspheres are prepared by a dispersion suspension solidification method. Compared with the prior art, low-temperature curing and one-shot molding
granulation are realized without requirements of high-temperature
calcination and curing and addition of other auxiliaries; and at the same time, large-scale use of
solid wastes is realized, and raw materials are widely available, cost is low, process is simple, and the whole process is non-toxic and
pollution-free; in addition, the preparation efficiency is high with a ball-forming degree exceeding 90%; the size of the particles can be adjusted, and the pore size distribution is uniform; the pore volume is large, and can be regulated, and a specific surface area of the microspheres reaches 110m2 / g, thus, the porous geological
polymer microspheres can be directly used for packed columns for column separation. Experiments show that the porous geological polymer microspheres have a good
adsorption effect on
heavy metals, and can be used as adsorbents for
heavy metals, and have a broad application prospect in the aspect ofremoving
heavy metals and radioactive elements in water.
