Abstract
Fast and selective separation of dimethyl phthalate, diethyl phthalate, dibutyl phthalate, di(2-ethylhexyl)phthalate (DEHP), benzyl butyl phthalate, diisodecyl phthalate, dimethyl adipate, diethyl adipate, di(2-ethylhexyl)adipate, triethyl citrate, tributyl citrate, tributyl acetyl citrate and n-butyl stearate have been developed on thin layers of inorganic ion-exchanger stannic silicate using a mixture of toluene + ethyl acetate (10:1, v/v) as mobile phase. The development distance and time were 12 cm and 25 min, respectively. Quantitative determination of DEHP was made at wavelength 280 nm by Camag TLC Scanner-3. Limit of quantitation for DEHP was 0.50 μg per zone while its limit of detection was 0.05 μg per zone.
