چکیده
|
Trivalent rhodium was determined spectrophotometrically as its 1:2 rhodium o-methylphenyl thiourea (ompt) complex,extracted into chloroform from aqueous acetate buffer media at ph 5.4. the complex exhibits maximum absorption at 320nm (molar absorptivity 9.76×103lmol-1cm-1),sandell's sensitivity 0.0105μg of rhodium(iii) cm-2. beer's law obeyed up to 10.0μg/ml. the method is free from a large number of interferences from cations and anions. the method is simple,selective and reproducible. it permits separation and determination of rhodium(iii) from synthetic mixtures corresponding to alloys. a scheme for mutual separation of palladium(ii),rhodium(iii),platinum(iv) and iridium(iii) has been developed. © 2012 .
