We speclated Inorganic tin and methyl-and n-butyltin compounds by volatilization from water samples by hydride generation, separation by a chromatographic packing material, and detection by atomic absorption spectrophotometry in an electrothermal quartz furnace at the 224.61-nm wavelength. Absolute detection limits of 20–50 pg (3σ) as Sn and linearity of calibration curves up to 30 ng as Sn avoid preconcentration by extraction and allow direct determination of methyl-and n-butyltin compounds from environmental waters. Reproducibility for 15 ng as Sn is less than 15% for most alkyltin compounds. This study discusses optimization of parameters and results from natural waters. © 1986, American Chemical Society.
