Summary 4(5)-D-Arabinotetrahydroxybutylimidazoline-2-thione, THBIT, is proposed as a new reagent for the spectrophotometric determination of Pd(II). Pd(II) forms 1∶1, 1∶2 and 1∶4 complexes with THBIT. The system conforms to Beer's law up to 5μg/ml palladium concentration in aqueous medium (molar absorptivity, 1.99×104 l· mole−1·cm−1 at 338 nm). The most serious interference is from Hg(II), Os(VIII), Ru(IV), Cr(VI), V(V) and S2O3 2−. The method has been used successfully for the determination of palladium in catalysts and synthetic samples.
