albumin

This article is devoted to researching the adsorption of high-molecular compounds in a column-type apparatus, which allows for taking into account the specific properties of adsorbed substances and the design features of the equipment. The purpose of the study was to create a mathematical model that describes the process of adsorption of high-molecular compounds in a column-type apparatus, taking into account the specific properties of the adsorbed substances and the design features of the equipment.

The article presents the results of the study of the kinetics of ions adsorption from multi-component mixtures. The isotherms of sorption of ammonium nitrogen in the presence of phosphates indicate a decrease in the exchange capacity of zeolite due to its competition for active absorption centres. This study was carried out with two ions of inorganic nature. In the presence of the third organic component in the solution (protein substance - albumin), the sorption capacity of zeolite decreases even more in comparison with ammonium ions.

The statics and kinetics of albumin adsorption on natural zeolite of clinoptilolite structure have been investigated. The basic characteristics of zeolite have been determined. The method of albumin in a solution analysis was given. An isotherm of albumin adsorption was plotted and the Langmuir equation describing this isotherm was given. The presence of an external and pore diffusion adsorption mechanism has been experimentally established during the study of kinetics in a machine with mechanical stirring.
