Determination of
Cr and study of its distribution in advanced materials based on tin oxide by
inductively coupled plasma mass spectrometry
Abstract
A novel approach
is developed for the determination of chromiumdopants by ICP-MSon
the surface and in the volume of advanced
materials based on tin oxide. Using KSCNis suggested for the
determination chromium on the surface without dissolving the tin. According to
the obtained data, 20% of chromium is on the surface of the material, 80% –
distributed in the volume. The distribution of chromium on the surface and in
the volume of SnO2 does not depend on the amount introduced in the
synthesis.
Key words:
nanomaterials, chromium, tin dioxide, Inductively Coupled Plasma Mass
Spectrometry.
