Abstract

In the article sorption capacity of 85% glauconite concentrate Beloozersk field Saratov region in relation
to the drug substance - tetracycline hydrochloride.
The aim is to study the sorption capacity of glauconite investigated in relation to tetracycline, obtaining
thermodynamic sorption parameters and evaluation of the kinetics and mechanism of the process.
The article presents the basic thermodynamic parameters of adsorption of tetracycline to glauconite,
studied the kinetics of the process. It is shown that the sorption of tetracycline occurs spontaneously. Some
considerations of the possible mechanisms of the process flow: chemisorption due to donor-acceptor interaction
and ion exchange processes. The results can be useful when using Beloozersk glauconite deposits, as a
filter material, post-treatment of wastewater from pharmaceutical companies such as the antibiotic tetracycline.
