Trace amounts of selenium and tellurium in high-purity iron were quantitatively separated by a reductive coprecipitation technique with palladium, and determined by electrothermal atomic absorption spectrometry. When ascorbic acid was used as reductant, selenium and tellurium could be simultaneously

The simple, sensitive, and highly selective determination of palladium is based on the reaction between Pd(II) and 1,2-bis[methyl(2-aminocyclopentene carbodithioate)] ethane and extraction of the complex into dichloromethane. Beer's law is obeyed in the concentration range 0.19-10 mg ml 01 Pd. Relat
o-Tolidine is known to react with free chlorine, gold(IXI), osmium tetroxide, ruthenium salts, tungstates, etc. la2 but it has not been applied to the determination ofruthenium via its reaction with rhthenium tetroxide. This procedure is less sensitive than the catalytic cerium-arsenic method 3, but
