Реферат: A mesoporous carbon sorbent modified with sulphosalicylic acid by adsorption from aqueous solutions has been synthesized. The optimal modification parameters were selected: the ratio, concentration, the duration of impregnation and heat treatment stages, and pH. The physicochemical properties of the samples have been stud- ied: textural characteristics, qualitative and quantitative composition of surface functional groups, the amount of applied modifier, adsorption and desorption properties. The adsorption characteristics of the studied samples with respect to organic dyes methylene blue and methanyl yellow are determined. It has been established that during desorption for 48 h, ~ 68% and ~ 82% of the initial concentration of sulphosalicylic acid applied to the sample pass into the aqueous solution, modelling the intestinal medium and into ethanol, respectively. In this case, a decrease in the pH of the initial solutions by 6 units is observed. High antibacterial properties of the modified carbon sorbent towards Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella pneumoniae have been established in vitro.
