| Abstract: | A method for extracting butyl-, cyclohexyl-, octyland phenyl-tin compounds in fruit juices was developed using 0.05% tropolone in 25% pentane/diethyl ether. Methyl derivatives formed by Grignard reaction were quantified by gas chromatography-atomic absorption spectrometry. Several fruit juices contained low ng cm?3 levels of butyl- and octyl-tins. Gas chromatography-mass spectrometry, used for the confirmation of the butyl- and octyl-tins, also detected phenyl- and cyclohexyl-tin compounds at levels below the GC AA detection limits (0.03–0.05 ng Sn cm?3). |
