| 英文摘要 | A rapid and solvent-free procedure for the simultaneous determination of mono-, di-, and tributyltin in sediments by headspace solid-phase microextraction (SPME) is described. The butyltin chlorides present in sediments were converted into their hydride forms by potassium tetrahydroborate prior to extraction. A quartz fiber coated with 100 mum film of polydimethylsiloxane (PDMS) is introduced into the headspace over the matrix to extract butyltin hydrides. After extraction, the fiber is directly inserted into the injector of the gas chromatograph (GC) for desorption, separation, and quantification. A laboratory modified flame photometric detector using quartz surface-induced tin emission (QSIL-FPD) was used throughout the experiment. The detection limits obtained with SPME-GC-QSIL-FPD for mono-, di-, and tributyltin are 8.8, 0.16, and 0.05 ng/g as Sn, respectively. The proposed method has been validated by analyzing standard reference material CRM-462, and successfully used for the determination of butyltin compounds in sediment collected from coastal areas of Hong Kong. |
