A very sensitive procedure for the determination of platinum in hydroponically cultivated plant samples ( Sinapis alba L and Lolium perenne) is presented. A microwave digestion with HNO 3 , HClO 4 and HCl acids with additional UV irradiation is followed by the platinum determination by adsorptive stripping voltammetry at hanging mercury drop electrode. The influence of HNO 3 acid on voltammetric determination of platinum is discussed. For validation of the obtained results the recovery of Pt was examined and the Pt determination by ICP MS was carried out. The highest platinum amounts were found in the roots of the plants, nevertheless the effective transport of platinum to the steams and leaves was also observed.
