Abstract
The use of an in-line photolysis coil in a continuous-flow system of high-performance liquid chromatography coupled with hydride generation and flame atomic-absorption spectrometry for the speciation of tin in natural waters is described. Irradiation with ultraviolet light is shown to convert tributyltin into organic tin(IV), from which a volatile hydride can be produced in the conventional way. The effect of various conditions on the analytical performance is discussed. A detection limit of 2 ng for tin was obtained, and the tin species could be completely separated within 6 min. Use of the technique for quantification of tributyltin compounds in local coastal waters is described.
