Tin was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) and high resolution-inductively coupled plasma mass spectrometry (ICP-MS) with a hydride generation technique. Stannane generated with sodium tetrahydroborate(III) (SBH) was separated from solution with a spiral tube in a closed vessel. The tin content in marine materials was determined by the present methods. Antimony(III) and antimony(V) were determined by ICP-AES or ICP-MS using the pre-reduction of antimony with L-cysteine. Also, arsenic(III) and arsenic(V) were determined by ICP-MS combined with the pre-reduction of arsenic. Tributyltin and triphenyltin in marine sediments were determined by gas chromatography-atomic absorption spectrometry (GC-AAS) with hydride generation. The chlorides in sediments spiked with a hydrochloric acid solution of 8-quinolinol were extracted into toluene. After the solvent had been converted to ethanol, it was applied to a Bondesil SCX. The organotin compounds were eluted with a methanol solution of hydrochloric acid and determined by GC-AAS after hydridization.
