Abstract
A rapid, simple isotope dilution method for detecting organotins in sediment samples.
Highlights
Tri-substituted organotin compounds, such as trialkyl- and triphenyltin (TPhT) have been extensively used as antifungal and antibacterial agents
A rapid method was developed for the determination of monobutyltin, dibutyltin, tributyltin, monophenyltin, diphenyltin, and triphenyltin by liquid chromatography-isotope dilution-inductively coupled plasma-mass spectrometry in sediments and drinking water
The chromatographic conditions were modi ed from the method reported by Chiron et al.,[6] who reported that plasma stability was superior when methanol was employed as the organic modi er, at the expense of separation efficiency
Summary
Tri-substituted organotin compounds, such as trialkyl- and triphenyltin (TPhT) have been extensively used as antifungal and antibacterial agents. Other uses of organotin compounds include plastics stabilisers,[1] wood preservatives, re retardants and reducing agents, as well as applications in the pharmaceutical, ceramic and glass industries.[2]. Trialkyltin compounds are extremely toxic biocides that are deliberately and directly released into the environment.[3] Trialkyltins, and in particular the tributyl-substituted species (TBT), are the active agents in marine antifouling paints. Their use has been regulated by the International Maritime Organisation (IMO) since 1990 4 due to their extreme toxicity toward aquatic organisms.
