Two liquid-liquid extraction procedures have been optimized for analysis of sea water samples. Tributyltin (TBT), dibutyltin (DBT), and monobutyltin (MBT) compounds were extracted with tropolone in chloroform from samples acidified to 1 M with HCl. The extracts were evaporated to dryness and redisso

An investigation of the extraction recovery of butyltin species in sediment by supercritical fluid extraction (SFE) is presented. Satisfactory recoveries for TBT (93.5 f 3.7%) and DBT (91.5 f 3%) are achieved. The recovery for MBT from spiked sediment (62 + 5.1%) is the highest value so far achieved
