The invention belongs to the technical field of adsorbents, and provides a composite adsorption material for
uremia and a preparation method of the composite adsorption material for
uremia. The preparation method comprises the following steps: mixing N, N '-
methylene bisacrylamide,
glycerol and deionized water, stirring, adding
sodium alginate, stirring for dissolving, sequentially adding
ammonium persulfate,
calcium sulfate and
tetramethylethylenediamine, stirring, performing ultrasonic treatment, and heating for reaction to obtain a
sodium alginate derivative; s2, mixing a
sodium alginate derivative and deionized water, adding modified high-density
polyethylene, stirring, and soaking in a CaCl2 solution for crosslinking to obtain a
sodium alginate composite material; s3, mixing the CeO2 / MoS2 functional material,
sodium alginate and deionized water, adding the
sodium alginate composite material, stirring, forming, soaking in a CaCl2 solution for crosslinking, washing and
drying to obtain the composite adsorption material. The composite adsorption material disclosed by the invention is high in adsorption rate and high in adsorption capacity on
uremia toxins, and has relatively good
biocompatibility and
blood compatibility.
