J. Planar Chromatogr. 10, 336-341 (1997). Description of a TLC technique for quantitative determination of hydrocarbons in waste water after extraction with n-heptane by means of a micro separator. TLC on silica with n-heptane and chamber saturation. Quantification by IR spectroscopy or after dyeing with acid violet 17 which gives detection sensitivities lower by at least one magnitude. The proposed technique also enables determination of other groups of potential contaminants by applying multiple step development.

J. Chromatogr. A 1458, 136–144, (2016). The soil-water partition coefficient normalized to the organic carbon content (KOC) influences the fate of organic compounds in the environment. This paper proposes a RP-TLC method for KOC determination as a simpler, yet equally accurate method as the official HPLC method. TLC on different systems, including RP-18 and cyano phases developed with methanol – water and acetonitrile – water mixtures. 50 different compounds such as phenols, benzodiazepines, triazine herbicides, and polyaromatic hydrocarbons were selected. A calibration set of 29 compounds with known logKOC values was used to build simple univariate calibrations, Principal Component Regression (PCR) and Partial Least Squares (PLS) models between logKOC and TLC retention parameters. The models exhibit good statistical performance and indicate that the cyano phase contributes better to logKOC modeling than the RP-18 phase. Comparison of the proposed TLC methods, the official HPLC method, and four in silico estimation approaches by using the non-parametric Sum of Ranking Differences(SRD) approach. The best estimations of logKOC values were achieved by simple univariate calibration of TLC retention data from cyano phase developed with 40–50 % methanol. In a Linear Solvation Energy Relationship study it was found that the more polar cyano phase in combination with methanol – water mixtures is the key to better modeling of logKOC through significant diminishing of dipolar and proton accepting influence of the mobile phase as well as enhancing molar refractivity in excess of the chromatographic systems.

Application of the method to the diphenylhexatriene ß-cyclodextrin complex in H2O/MeCN system enables the separation of free and bound DPH and an accurate estimation of their respective quantities on the plate. Evaluation of free DPH eluted with the hydrocarbon media by comparison of emitted fluorescence intensity with the linear 0 to 50 pmol calibration scale. Dissociation of DPH bound to BCD with a brief polarmigration followed by elution with a non polar solvent mixture and evaluated as above.
