For characterization of corrosion resistance of metallic biomaterials, determination of trace amounts of metallic ions released from the materials in static immersion into simulated body fluids were investigated. In a pre-treatment method by sulfuric acid, sensitive, precise and accurate determination of the trace metallic elements in simulated body fluids could be performed by an inductively coupled plasma-optical emission spectrometry. For accurate analysis, it was necessary to employ a matrix-matched solution for the calibration. Moreover, usage of a vessel made of tetrafluoro ethylene-perfluoro alkylvinyl ether copolymer in the static immersion test was recommended for the prevention of contamination. Thus, it was possible to determine μg dm -3 order of elements in simulated body fluids and evaluate nano-gram order of the released metallic ions.
