 Yttrium was determined by means of the resonance light scattering (RLS) technique. The characteristics of resonance light scattering spectra of yttrium-1, 6-bi(1′-phenyl-3′-methyl-5′-pyrazolone-4′-) hexanedione (BPMPHD), the effective factors and optimum conditions were studied. In the pH range of 5.0–6.1, yttrium-BPMPHD complex produces three characteristic peaks of RLS at 365, 402 and 467 nm. The enhanced intensity of RLS is proportional to the concentration of yttrium in the range of 1.0¡Á10−8 to 1.0¡Á10−5 mol ¡¤ L−1. The limit of detection is 5.9¡Á10−9 mol ¡¤ L−1. The method has been used for the determination of Y3+ in mixed rare earths.
