This invention relates to the field of biomedical technology, and provides an NH4 + Biotransformation scavenging materials and their preparation methods utilize glutamate dehydrogenase to decompose urea into NH4, which is generated by urease. + α-Ketoglutarate and nicotinamide adenine dinucleotide are converted into glutamate under the action of enzymes, thereby removing NH4, which is highly toxic to the human body. + Furthermore, MAF-7 material was synthesized by reacting zinc nitrate and 3-methyl-1,2,4-triazole in aqueous solution. Simultaneously, glutamate dehydrogenase was added during the synthesis process to immobilize the enzyme in situ onto MAF-7. This material can regenerate NH4+, a byproduct of peritoneal dialysis fluid regeneration in WAK. + It can effectively remove NH4 and also achieve long-term continuous removal. + This reduces the amount of adsorbent used and the size and weight of the device, further improving the urea treatment efficiency and solving the Na+ problem in the REDY system. + H + Risk of leakage.
