Problems solved by technology

However, during the course of treatment, the supply of dialysate becomes tight and in short supply
[0003] The current clinical use of dialysis machines severely restricts their use due to the disadvantages of large floor space, large waste fluid production, and low efficiency in removing toxins.

Abstract

The invention discloses a method for rapidly preparing a hydrogen bond organic framework material based on an electric field, and application thereof. The method comprises the following steps: (1) weighing raw materials; (2) dissolving an organic ligand in an organic solvent, and adding another organic solvent after the organic ligand is completely dissolved; and (3) introducing direct current with a certain voltage into the solution mixed with the organic ligand, and centrifuging, washing and drying the product for multiple times to obtain the hydrogen bond organic framework material. According to the present invention, the hydrogen bond organic frame preparation time is shortened by promoting the formation of the hydrogen bond under the action of the external electric field, and the rapid and efficient removal of the small and medium molecular toxins during the hemodialysis process is achieved by using the large specific surface area and the porous structure of the hydrogen bond organic frame, and the good biocompatibility and the reusability of the hydrogen bond organic frame.

Description

Technical field: [0001] The invention relates to a method and application for rapidly preparing a hydrogen-bonded organic framework material based on an electric field, and belongs to the field of hydrogen-bonded organic frameworks. Background technique: [0002] More than 3 million people worldwide are currently affected by end-stage kidney disease. Dialysis or kidney transplantation is the only option for these patients to avoid death, but only a few lucky people can undergo kidney transplantation, and the vast majority of them rely on dialysis. Chronic dialysis patients are mostly disabled, unable to perform normal activities of daily living, have poor quality of life and high mortality. To reduce the impact of end-stage renal disease in these patients, frequent and prolonged dialysis treatments are required. Furthermore, the COVID-19 pandemic has become a major worldwide crisis. Although respiratory symptoms are a key feature of the disease, many patients with COVID-19...
