The paper describes the preparation of new
analytical forms of rhodium(III) compounds with flavonoids (morin and quercetin) and its rapid spectrophotometric
determination in the intermetallic compounds HoRhIn5
and LaRhIn2. The concentration ranges of the rhodium ions with morin and quercetin were equal to
0.08-1.50 µg/ml (Сmin = 0.030 µg/ml) and
0.05-2.55 µg/ml (Сmin = 0.012 µg/ml),
respectively.
