description: This work is devoted to the development of a technology for obtaining sorbents based on synthetic magnesium silicate with the maximum possible specific surface area, the study of the influence of the parameters of sorbent synthesis on the properties of its surface, and the creation of equipment for rapid analysis of the specific surface by the BET method. Theresearch set the following goals:1)Investigation of the effect of reagent concentration on the morphol-ogy of the final structure of the sorbent and its specific surface area2)Study of the effect of the method of introducing reagents on the final properties and structure.3)Investigation of the effect of the rate of reagent administration on the morphologyof the final structure of the sorbent and its specific sur-face area4)Study of the influence of the nature and composition of the reagents on obtaining the final structure.5)Study of the parameters of filtration and washing of sediment6)Study of the parameters of drying and annealing of the sorbent.7)Development of a technique for introducing magnetic particles into the structure of the adsorbent8)Creation of a multi-channel express analyzer of the specific surface area "TIM 2.4" and the study of sorbents on it by the BET methodIn the course of the work, the influence of the concentration of rea-gents, the method of synthesis, the rate of introduction of reagents, the nature of the reagents used, the parameters of drying and annealing on the specific surface of the sorbent was investigated. A technology for producing a mag-netic adsorbent based on magnesium silicate and a Fe3O4 magnetic core was also developed. The TIM 2,4 express surface area analyzer was designed,calibrated,and successfully used in the research.As a result of this work, a technology has been developed the produc-tion of sorbents based on magnesium silicate with high specific surface area values, which can be used for the purification of polar organic liquids from polar pollutants, for example, the purification of edible oils, the purification of industrial oils and lubricants, and the purification of biodiesel. The de-signed BET analyzer can be used in laboratories of universities or enterprises where there is a need to conduct studies of large number of samples.
