Highly sensitive catalytic waves of OsO 4-bromate linear sweep voltammetric and square
wave voltammetric techniques were proposed for the determination of ultratrace amounts of
osmium. Under optimized conditions, the catalytic linear sweep voltammetric procedure
gives excellent reproducibility and limits of detection and a linear dynamic range and gives a
low signal for background, whereas the square wave voltammetric technique gives higher
sensitivity, but the background signal was high and the linear dynamic range was ...
