[Determination of Ag ions in water, urine and blood].
Developments in polarography techniques over the last thirty years have enabled us to register outstanding increases in sensitivity: the order of concentration studies has evolved from 10(-3) g ions/1 to 10(-10) g ions/1. Pulse polarography with anodic stripping voltammetry is therefore particulary suitable for the determination of numerous metals which are to be found in extremely low concentration in biological samples which may be of limited volume e.g. blood. Our objects has been to describe and to apply in the case of silver a determination technique which would be sufficently sensitive, precise, practical and rapid for it to be easily used by biologists and toxicologists. A fortiori, this method may be applied in hydrology to the determination of these metals in water.
