Abstract

The article presents the results of research on the primary characteristics of hybrid or-ganomineral sorbents based on silica gel modified with a mixture of polyvinyl alcohol
and liquid glass (PVS : Na2SiO3). The relevance of the topic is due to the search for highly
effective sorbents for the development of analytical test systems and chromatographic
analysis. As a result of the work, the true density, strength, water absorption capacity, as
well as absorption capacity in relation to methylene blue and iodine were evaluated. It was found that an increase in the concentration of liquid glass in the modifying mixture leads to a decrease in the absorbing properties of sorbents in relation to both methylene blue and iodine. Analysis of the obtained experimental data allows us to classify the obtained sorbents as mesotype sorbents. The study revealed that the most effective is the ratio of polyvinyl alcohol and liquid glass 20 : 10.
