Abstract

Platinum (Pt) is a malleable, ductile, silver-white metal with atomic number 78 and an atomic weight of 195.09. Platinum is found in nature in metallic state, alloyed with small amounts of iron, copper, other platinum metals, and sometimes with little gold. This ore appears as granules or nuggets, weighing from a few milligrams to a few pounds, scattered in a silicate (olivine and piroxene). Urine samples (10 ml spot), were collected from patients admitted to the Clinical Toxicology Section. Expert literature recommends the determination of platinum in the normal population of the area as the amount of platinum present in the environment differs. For determination of platinum in biological products an installation consisting of Atomic Absorption Spectrometer Model AAS-880, Atomizing in graphite furnace model GT 100, Autosampler model PSD - Varian. Graphite Furnace Atomic Absorption Spectroscopy (GF-AAS) optoelectronic method presented is a fast, reproducible, with a very good sensitivity for monitoring population or staff exposed to platinum and its compounds.
