摘要：

An investigation of the extraction recovery of butyltin species in sediment by supercritical fluid extraction (SFE) is presented. Satisfactory recoveries for TBT (93.5 +/- 3.7%) and DBT (91.5 +/- 3%) are achieved. The recovery for MBT from spiked sediment (62 +/- 5.1%) is the highest value so far achieved by the SFE technique. A comparison of the supercritical fluid extraction with the improved tropolone solvent extraction technique for the butyltin species is presented. The results of the analysis of a reference sediment (PACS-1) are also given.
