The extractive and separation properties of poly[dibenzo-18-crown-6] are studied for palladium (II). In present study, poly [dibenzo-18-crown-6] was used as a sorbent for chromatographic extraction and separation of palladium (II) in glycine medium. At optimized conditions the sorbent shows greater than 98% recovery for palladium(II) ion. The separations are carried out using glycine medium. palladium(II) uptake was quantitative from 1x10-7 to 5x10-1M glycine. Palladium(II) was quantitatively eluted with 3.0–8.0 M HCl, 2.0-5.0 M HClO4 ,4.0-8.0 M HBr and 4.0-8.0 M H2SO4 ,while CH3COOH was not an effective eluent for palladium(II) .The sorption capacity of poly [dibenzo-18-crown-6] was found to be 0.845±.0.1 mmol /g . The sorption study of Palladium(II) as function of glycine, capacity of poly[dibenzo-18-crown-6] , effect of interfering ion and elution profile has been studied. palladium(II) was separated from multi-component mixtures. The developed techniques of palladium(II) ion is simple, effective with good stability and reproducibility (approximately ± 2%).
