Abstract

The invention relates to nano molybdenum sulfide and application of the nano molybdenum sulfide as an efficient adsorbent for uremia toxin. The technical problems that in the prior art, an adsorption material in a dialysate purification device capable of wearing an artificial kidney is difficult to store, the adsorption efficiency is low, and the biocompatibility is poor are solved. The nano molybdenum sulfide has a two-dimensional ultrathin nanosheet structure, a large number of defects exist on a basal plane due to the interlayer spacing, and the molybdenum disulfide with wide interlayer spacing and rich lattice defects can be used as an efficient adsorbent for uremia toxins. The invention reports that molybdenum disulfide with wide interlayer spacing and rich lattice defects is used for adsorbing uremia toxins urea, creatinine and uric acid for the first time. Compared with commercial MoS2, activated carbon, narrow-interlayer-spacing MoS2 with lattice defects and narrow-interlayer-spacing MoS2 without lattice defects, the dialysate purification material with high adsorbability, high selectivity and high stability is obtained by analyzing and researching the adsorption performance of the material under different conditions (adsorbent dosage, adsorption time, temperature and the like).

Description

technical field [0001] The invention relates to the technical field of dialysate purification materials, in particular to a nano-molybdenum sulfide and its application as an efficient adsorbent for uremic toxins. Background technique [0002] The removal of uremic toxins (urea, creatinine, uric acid, etc.) in dialysate purification devices that can be worn with artificial kidneys is a recognized challenging topic. The currently studied adsorbent substitute materials are Ti 3 C 2 T x lamellar maikeene (MXene), titanium dioxide (TiO 2 ) electrodes and porous activated carbon, etc. However, most of the adsorbent materials used for the removal of uremic toxins severely limit their applications due to their complex preparation, single adsorption properties, no selectivity, low adsorption properties, and poor biocompatibility. SUMMARY OF THE INVENTION [0003] The invention aims to solve the technical problems of difficult storage of adsorption materials, low adsorption eff...
