Embodiment 1-4

[0075] Weigh a certain amount of P123 into a beaker, then add appropriate amount of hydrochloric acid and water, so that the molar concentration of hydrochloric acid is 1.18M, ​​1.34M, 1.49M and 1.65M respectively, put the beaker in a 37°C water bath and stir Dissolve P123; after P123 dissolves, add a certain amount of ethyl orthosilicate under strong stirring, so that the molar ratio of the substances in the solution is: SiO 2 :P123:H 2 O=1.00:0.016:180, continue to stir for 5 minutes and immediately transfer the sol to a hydrothermal kettle and place it in a constant temperature oven at 120°C for 24 hours, then wash the obtained block with distilled water and keep it at a constant temperature of 100°C Dry in an oven overnight, and then calcine in a muffle furnace at 550° C. for 6 hours to remove the surfactant P123, so as to obtain each matrix-silica block. It was found that the concentration of hydrochloric acid in the range of 1.18-1.65M can get a complete block ( figure...

[0081] Weigh a certain amount of P123 into a beaker, add appropriate amount of hydrochloric acid and water to make the molar concentration of hydrochloric acid 1.49M, put the beaker in a 37°C water bath and stir to dissolve the P123; Add a certain amount of ethyl orthosilicate under strong stirring, so that the molar ratio of the substances in the solution is: SiO 2 :P123:HCl:H 2 O=1.00:0.016:5.00:180, after continuing to stir for 5 minutes, immediately transfer the sol into a hydrothermal kettle and place it in a constant temperature oven for 24 hours. The temperatures of each constant temperature oven are respectively: 110, 120, 130, 140, 150 and 170°C, and then the obtained block was washed with distilled water and dried overnight in a constant temperature oven at 100°C, and then calcined in a muffle furnace at 550°C for 6 hours to remove the surfactant P123 to obtain each precursor - Silica bulk. It was found that hydrothermal temperatures in the range of 110–170°C yield...

Abstract

The invention relates to a mesoporous / macropore hierarchical pore block bilirubin adsorbent material and a preparation method of the mesoporous / macropore hierarchical pore block bilirubin adsorbent material. The mesoporous / macropore hierarchical pore block bilirubin adsorbent material is prepared by using a hierarchical pore silicon dioxide block material as hard template negative type, wherein the adsorbent material is in a three-dimensional network structure which is formed by assembling and interconnecting micron-sized short bars with ordered mesoporous structures; a pore channel of the network is a macropore. The invention also provides a method for preparing the mesoporous / macropore hierarchical pore block bilirubin adsorbent material. The mesoporous / macropore hierarchical pore block bilirubin adsorbent material is high in specific surface area; the material is block type, the mechanical strength is high, so that the situation that the material is broken and particles fall off can be avoided, and the material is applicable to blood perfusion, high in absorption rate of bilirubin and high in absorption capacity of the bilirubin; along with the increase of the concentration of the bilirubin, equilibrium adsorption capacity for the bilirubin of the material is increased; and the mesoporous / macropore hierarchical pore block bilirubin adsorbent material is a novel bilirubin adsorbent material which is high in rate and high in adsorption capacity.

Description

technical field [0001] The invention belongs to the field of mesoporous materials and relates to a novel mesoporous / macroporous multi-level porous block bilirubin adsorbent material. The invention also relates to a preparation method of the mesoporous / macroporous multi-level porous block bilirubin adsorbent material. Background technique [0002] Toxins in the human body can be roughly divided into two categories: exogenous toxins and endogenous toxins. The former are toxic substances from outside the body (such as pesticides, sleeping pills, etc.), and when they accumulate too much in the human body, they will cause various diseases; Toxic substances (such as bilirubin, bile acid, uric acid, etc.) formed by accumulation can also cause various lesions. Under normal circumstances, the human body can detoxify, remove or neutralize endogenous or exogenous toxins through its own protection systems such as the liver detoxification system, the body's own immune system and excret...
