Simultaneous determination of two
components of nickel silver by digital colorimetry
Abstract
A simple and cheap method for the
simultaneous determination of high copper(II) and nickel(II) concentrations in
aqueous solutions was developed, based on the formation of their colored
complexes with the subsequent digital colorimetric analysis using an office
flatbed photo scanner. Its validity was verified by the analysis of a nickel
silver standard sample. The difference between the accuracy of copper and
nickel determination using digital colorimetry and spectrophotometry was
negligible.
Key words: digital colorimetry,
two-component analysis, nickel silver, copper, nickel.
