Abstract
The invention provides a blood fat adsorbent and a preparation method thereof. The preparation method comprises the following steps: firstly, carrying out an activation reaction on an adsorption carrier by using polyepoxy glyceryl ether to obtain an activated carrier containing polyepoxy groups; adding a ligand into an acid solution to obtain a ligand solution; and adding the obtained activated carrier containing multiple epoxy groups into a ligand solution, mixing and stirring to perform a coupling reaction, and after the reaction is completed, performing solid-liquid separation, cleaning and drying to obtain the blood fat adsorbent. The coupling reaction is carried out under the acidic condition, and the acid is used as a catalyst for coordinating oxygen atoms of epoxy groups and promoting ring opening, so that the reaction rate of the coupling reaction and the utilization rate of ligands can be improved, the reaction temperature can be reduced, a complex catalyst is not used, pollution is reduced, the cost is saved, and the adsorption efficiency of the adsorbent is improved.
