Potentiometric Determination of Silver Nanoparticles using Silver Amalgam Electrodes

Abstract

A new approach to potentiometric measurements using an advanced amalgam electrode is reported. The conditions for the potentiometric determination on silver solid amalgam electrodes to determine total silver as colloidal silver nanoparticles are described. Proper calibration procedure was demonstrated by the potential and logarithmic concentration dependence at the silver amalgam and reference silver disc electrodes for aqueous silver nitrate.
