DETERMINATION OF ORGANO-TIN COMPOUNDS IN MARINE WATER

For the account and precise determination of trace amount of organo-tin compounds in marine water, gaschromatography-mass spectrometry was used with internal standards. Two types of internal standards were examined, one with deutrated homologues for isotope dilution and the other was tripentyltin compounds, both of which gave improved accuracy and precision. Analytical result is also given for the marine water samples at Aburatsubo bay where organo-tin concentration is still high due to leasure boat activity.
