Preservation of organics : part IV : stability of BIS (tri-n-butyltin) oxide in sediment extracts / by W.C. Li, S.Z. Zhang, Y.K. Chau and A.S.Y. Chau. : En13-5/90-139E-PDF

"This report summarizes the results for the preparation and stability of sediment extracts fortified with bis(tri-n-butyltin) oxide (TBTO). The analysis of TBTO in sediment extracts involved solvent exchange, chemical derivatization with ethyl Grignard reagent and analysis of the resulting ethyl derivative (ethyl-tributyltin) by GC/AAS. Stability of TBTO in sediment extracts was investigated under two storage conditions, namely 4°C and 25°C in the dark. Analytical results indicated no degradation of TBTO occurred in the two fortified sediment extracts for a minimum of 4 months"--Abstract, page iii.
