ADSORPTIVE STRIPPING VOLTAMMETRY OF INDIUM MORIN COMPLEX

Abstract

A very sensitive adsorptive stripping voltammetric method is studied on the In-morin complex at a HMDE in 0.1M acetate buffer (pH=3.20) solution. The effects of various analytical conditions are discussed on the reduction peak current of the adsorbed complex on the surface of HMDE. Interferences by other trace metals and surfactant are also discussed. Detection limit is 2.6nM of indium with 90 seconds deposition time, and the RSD (n=7) at 4μg/l indium is 2.0%.
