Rezumat:

The lipophilicity of some emerging pesticides is investigated by
reversed-phase high performance thin-layer chromatography (RP-HPTLC)
on RP-18, RP-8 and CN stationary phases. The mobile phases were mixtures
of methanol-water in different proportions of volume. The lipophilicity indices
taken in consideration during this study are: RM0, mean of RF and RM, b, φ0,
scores corresponding to the first principal components of RM and RF. The
obtained results are compared with the computed lipophilicity indices (Log P)
in order to evaluate the suitability of the involved method in the lipophilicity
estimation for the pesticides. The comparison is performed through correlation
matrices and profiles. The obtained correlations are indicating a high statistical
significance.
