| Abstract: | A theoretical analysis of the experimental data on absorption (desorption) of volatile organic compounds by (from) molecularly
imprinted polymer films was performed. The theoretical time dependences of the amount of absorbed analyte in a film were calculated
using a system of equations with four kinetic parameters (Γ, K, K
sur
, and C
eq
), which were determined by theoretically approximating the experimental data. The special features of the absorption-desorption
process in a polymer film were suggested to be described using a parameter called the specificity coefficient. Specificity
coefficients were determined for all the polymers and analytes studied. The specificity coefficients obtained from the chromatographing
data were compared with the imprinting factors of chromatograms calculated from the experimental retention time values. An
empirical linear dependence of specificity coefficients on imprinting factor values was obtained. |
