Influence of the acid groups on activated carbon on the adsorption of bilirubin

In order to study the influence of the acid groups on activated carbon to the adsorption of bilirubin, a commercial activated carbon was modified and a series of activated carbons with varying amount of acid groups, along with their surface texture changed was obtained. Then the effect of acid groups and mesopores on the surface of modified activated carbons on adsorption of albumin-bound bilirubin and free bilirubin were investigated. Results indicated that the adsorption capacities of albumin-bound bilirubin were improved by the increasing acid groups introduced on the surface of modified activated carbons, in spite of the significantly reduced mesopores. The adsorption capacities of free bilirubin rise both with the elevated acid groups and mesopores.

Automated summary

The presence of acid groups on modified activated carbon positively influences the adsorption capacity of albumin-bound bilirubin while significantly reducing mesopores, but both acid groups and mesopores contribute to the increase in adsorption capacity of free bilirubin.
