摘要：
It was shown that the process of dynamic sorption concentration of organic compounds of different natures on hydrophobic sorbents can be described in terms of the linear model of sorption dynamics. Using the model, the thermodynamic (distribution coefficient) and kinetic (mass-transfer coefficient) parameters of sorption were calculated. Optimum conditions were determined for the concentration of phenol on highly crosslinked polystyrene and 4-nitrobenzaldehyde N,N-dimethylhydrazone on silica chemically modified with hexadecyl groups from aqueous solutions.
