Determination of rhodium by resonance light-scattering technique coupled with solid phase extraction using Rh(III) ion-imprinted polymers as sorbent

► A resonance light-scattering(RLS) method for determination of Rh(III) was developed. ► A Rh(III) ion-imprinted polymer (IIP) was prepared as sorbent for SPE of Rh(III). ► The effects of variables on extraction efficiency and selectivity of IIP-SPE were studied. ► The RLS was coupled with IIP-SPE for separation and determination of Rh(III) in real samples.
