摘要：

A method for simultaneous determination of three organotin compounds named monobutyltin (MBT), dibutyltin (DBT), tributyltin (TBT) in seawater sample was described. The method was based on derivatization with sodium tetraethylborate followed by headspaced-solid-phase microextraction (SPME) combined with gas chromatography-flame ionization detector (GCFID). The SPME conditions were optimized using experimental designs (five factors and for levels). The calibration ranges of MBT, DBT and TBT are 0.05~1000 μg·L-1, 0.02~1000 μg·L-1, 0.02~1000 μg·L-1(as Sn). The detection limits of MBT, DBT and TBT are 50, 8, 8 ng·L-1(as Sn). The recoveries of MBT, DBT and TBT are 106%, 89%, 91% by analyzing seawater spiked with organotin compounds. Six samples taken from six cities (Shenzhen, Shanghai, Lianyungang, Qingdao, Dalian, Yantai) were analyzed, and organotin compounds were detected in all five samples but Qingdao.
