Selective Solid Phase Extraction for Separation and Preconcentration of Palladium from Gold Ore and Anode Slime after Complexation with a N4O2 Mixed Donor Ligand Derivative

A selective and sensitive method for the preconcentration, separation, and determination of palladium with flame atomic absorption spectrometry using 4,15-bis[(4-methylphenyl)sulfonyl]-20,21-dinitro-2,3,4,5,6,7,9,10,12,13,14,15,16,17-tetradecahydro- 8,11-ethano-1,18,4,8,11,15-benzodioxa tetraaza cycloicosine (TNACIN) on XAD-2010 was developed. TNACIN-Pd(II) complex formed acidic aqueous solution (0.075-0.100 M HNO3) was accumulated on XAD-2010 and then eluted with 1 M HCl in acetone. The effects of some analytical parameters including pH, TNACIN amount, sample volume, eluent type, and concentration, sample flow rate and matrix ions were studied for optimization of the method. Detection limit and precision were calculated for Pd(II). This method was also verified with CRM and internal standard, and satisfactory results were obtained.

The reaction of naphthalene-2,3-diol 1 with PCl3 was found to furnish the hydridophosphorane 3, with PCl5 the chlorophosphorane 4 was formed. The reaction of the fluorophosphoranes, RPF4 [R=F, (i)Pr, CH2SiMe3, CH2Cl, Ph] with the bis(trimethylsilyl) derivative of 1, 2 yielded the corresponding spirocyclic phosphoranes, 5-9 by cleavage of the Si-O bond and elimination of Me3SiF. The difluorophosphoranes, R2PF3 [R=Me, Ph] reacted with 2 to form the monocyclic phosphoranes, 10 and 11, where the fluorine atom occupies an axial position at trigonal-bipyramidal (TBP) phosphorus- The structure of compound 11 was confirmed by single crystal X-ray analysis of its dichloromethane hemisolvate at -95-degrees-C. The geometry at phosphorus is trigonal-bipyramidal. whereby the naphthalenedioxy ligand spans an axial and an equatorial site. Me2PF3 reacted with tetrakis(1,2,4.5-trimethylsiloxy)benzene to form the bifunctional benzodioxa-lambda5-phosphole, 12.
