Adsorption characteristics of LDL by dextransulfate-cellulose gel.

Abstract

The adsorption performance of dextransulfate-cellulose gel for low-density lipoproteins (LDL) in human plasma was investigated.Considering the mathematical model for the mass transfer of LDL, it was found that mass transfer was limited by pore diffusion within the gel. Maximum adsorption efficiency was obtained by the gel with an effective internal volume fraction in the range from 0.65 to 0.7.
