Simultaneous determination of tributyltin and triphenyltin in laver by high performance liquid chromatography with inductively coupled plasma mass spectrometry
Abstract：A new method was developed to simultaneous determine the tributyltin(TBT) and triphenyltin(TPhT) in laver by high performance liquid chromatography with inductively coupled plasma mass spectrometry(HPLC-ICP-MS).The laver sample was ultrasonically extracted with ethyl acetate-hexane(1/1,V/V) and dispersively purified by activated carbon as solid phase material.The sample extracts were determined by HPLC-ICP-MS.The chromatographic separation condition of TBT and TPhT was optimized.The results illustrated good linearities between the analytical signal and analyte concentration in the range of 4.0-20 μg·L-1 with the correlation coefficients being 0.999 0-0.999 1.The detection limits of TBT and TPhT were 0.37 and 0.49 μg·L-1,respectively.In the three spiked level,the average recoveries of TBT and TPhT located in the range of 96.8%-112.6% with relative standard derivation of 3.2%-9.3%.The proposed method is rapid,accurate and could be used to simultaneously detect TBT and TPhT in laver.
