ROJAS, Carlos León. Simultaneous Ultra Traces Voltammetric Determination of Platinum and Rhodium Using Adsorptive Preconcentration and Catalysis. Port. Electrochim. Acta [online]. 2005, vol.23, n.1, pp.139-163. ISSN 0872-1904.

It was evaluated a voltammetric method with adsorptive preconcentration and catalysis, using the hanging mercury drop electrode, for the simultaneous determination of ultra traces of platinum and rhodium. The optimized conditions were obtained after the sequential optimization, obtaining linearity until 6.00 ng/L for platinum and 0.7 ng/L for rhodium. The detection and quantification limits are 4.0 ng/L and 10 ng/L for platinum and 1.0 ng/L and 3.0 ng/L for rhodium.

Keywords : platinum; rhodium; ultra traces; voltammetry; determination; environmental.
