A method for the spectrophotometric determination or tin has been described which involves the extraction or tin(II) xanthate complex into chloroform. The yellow coloured complex shows λmax at 350 nm. Beer's law is valid over the range 1-20 µg Sn/ml with a Sandell sensitivity of 0.013 µg cm-2• Interference studies have been carried out. Gun metal and some synthetic samples have been analyzed to test the applicability of the method.
