Embodiment 1

[0033] Mesoporous silica SBA-15 is directly used for the adsorption of bilirubin after calcination to remove the surfactant. The specific surface area of ​​mesoporous pure silica SBA-15 is 775m 2 / g, the average pore diameter is about 6.8nm (see Table 1). By examining the variation of the adsorption capacity of bilirubin on mesoporous SBA-15 with time, it can be seen that the adsorption can reach equilibrium after 2 hours, and the equilibrium adsorption capacity of the material (such as Figure 5 shown). When the initial concentration of bilirubin solution was 500mg / l, when the equilibrium adsorption was 3 hours, the bilirubin equilibrium adsorption capacity of SBA-15 was 37mg / g (as Figure 6 shown). As the initial concentration of bilirubin increases, the equilibrium adsorption capacity of the material to bilirubin also increases; when the initial concentration of bilirubin increases to 1200 mg / l, the equilibrium adsorption capacity of the material to bilirubin Capacity up...

Embodiment 2

[0038] The specific surface area of ​​the monoamine-modified mesoporous material 1N-SBA-15 has decreased compared with pure mesoporous silica SBA-15, and the specific surface area is 373m 2 / g, the average pore diameter is about 6.0nm (see Table 1). When the initial concentration of bilirubin solution was 500mg / l, when the equilibrium adsorption was 3 hours, the bilirubin equilibrium adsorption capacity of 1N-SBA-15 was 51mg / g, which was larger than the adsorption capacity of pure mesoporous silica (as shown in the table 1). As the initial concentration of bilirubin increases, the equilibrium adsorption capacity of the material to bilirubin also increases; when the initial concentration of bilirubin increases to 1200 mg / l, the equilibrium adsorption capacity of the material to bilirubin Capacity up to 110mg / g (such as Figure 6 shown).

Embodiment 3

[0040] The specific surface area of ​​the diamine-modified SBA-15 is 336g, and the average pore diameter is about 6.1m (see Table 1). By examining the variation of the adsorption capacity of bilirubin with time on mesoporous SBA-15, it can be seen that the adsorption can reach equilibrium after 2 hours, and the equilibrium adsorption capacity of the material (such as Figure 5 shown). When the initial concentration of bilirubin solution was 500mg / l, when the equilibrium adsorption was 3 hours, the bilirubin equilibrium adsorption capacity of 2N-SBA-15 was 47mg / g (as shown in Table 1). As the initial concentration of bilirubin increases, the equilibrium adsorption capacity of the material to bilirubin also increases; when the initial concentration of bilirubin increases to 1200 mg / l, the equilibrium adsorption capacity of the material to bilirubin Capacity up to 105mg / g (such as Figure 6 shown).

Abstract

The invention relates to a mesoporous medical adsorption material, belonging to the field of mesporous material. The mesoporous adsorbent material of the invention has orderly mesoporous opening structure and composition of SiO2; amino modification of the surface of the material can be carried out. The adsorbent material of the invention can carry out the medical adsorption on various harmful matters such as bilirubin, cholic acid, uric acid, etc., and has good adsorption effect.

Description

technical field [0001] The invention relates to a class of mesoporous medical adsorbent materials, belonging to the field of mesoporous materials. 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 inside 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, [0003] The human body can detoxify, remove or neutralize endogenous or exogenous toxins through its own protection systems such as the liver detoxification system, the human body's own immune system and excretion system. However, for acute drug poisoning, uremia, kidney failure, liver failure and other diseases, the human body basically loses its ability to d...
