Simultaneous
Determination of Rhodium and Gold
micro environment of
reagents and analytes, and control the reactivity,
equilibrium and
pathway of chemical or photochemical processes /5,6/.
In the present paper,
the reactions of Au (III) and Rh (III) with p-DABR
in the presence of
cationic [cetyltrimethylammonium bromide, CTAB]
surfactant have been
studied. Simultaneous photometric determination of Au
(III) and Rh (III) is
hampered due to spectral overlap of their complexes. In
such cases
spectrophotometry coupled with derivative techniques is useful in
analysis of such
mixtures Π-91. In this work derivative spectrophotometry
was also used to
improve the sensitivity and selectivity /ΙΟ,II/. As the
proposed methods are
practically free from interferences, they have been
applied to Rh (III) and Au (III)
determination in synthetic samples.
