Abstract
A method for the determination of tributyltin (TBT) in tissue and sediments has been developed for environmental samples. The technique involves extraction with methylene chloride and isolation of TBT from mono- and dibutyltin with a sodium hydroxide wash. The TBT is then back extracted and converted to elemental Sn with nitric acid. Analysis is by Zeeman graphite furnace atomic absorption spectrophotometry. Recoveries of spiked samples were between 99% and 111% for mussel and fish tissues and 72% and 99% for various sediments. The limit of quantification was 0.0025 ..mu..g/g for tissue (on a wet weight basis). This technique was developed in response to their need to process large numbers of environmental samples with a minimum time investment.
