On-line preconcentration and separation of palladium, platinum and iridium using α-amino pyridine resin with flame atomic absorption spectrometry

Chelating Resins and Their Applications in the Analysis of Trace Metal Ions

“…Modified polyphenylethylene has been reported for the preconcentration and separation of noble metals (11,12). Recently, an on line preconcentration and separation of palladium, platinum, and iridium using ␣-aminopyridine-polyphenylethylene resins by means of AAS were reported with a detection limit of 0.017, 0.009, and 0.11 g ml Ϫ1 and relative standard deviation (RSD) of 2.9, 1.3, and 3.8% for Pt 4ϩ , Pd 2ϩ , and Ir 3ϩ , respectively (11).…”

Synthesis, characterization, and properties for Hg2+ of new chelating resin containing sulfoxide and 3‐aminopyridine

“…1 Chelating resins with covalently bonded heterocyclic functional groups possess excellent adsorption and selectivity properties for metal ions, especially for heavy metal ions. Such heterocyclic functional groups as pyridine, 2,3 imidazole, 4,5 thiodiazole, 6,7 2-mercaptobenzothiazole, 8,9 etc., have been introduced into polymeric matrix. Among the aforementioned heterocyclic functional groups, aminopyridine receives a lot of attention because of its strong affinity for noble and heavy metal ions.…”

Application of artificial neural networks in multivariable optimization of an on-line microwave FIA system for catalytic kinetic determination of iridium(III)

“…The sophisticated techniques, e.g. graphite furnace laser-induced fluorescence spectrometry and flow injection isotope dilution inductively coupled plasma mass spectrometry have been used for the determination of iridium [1,2,3,4,5]. However, these analytical methods have problems with hardly available high-cost instrumentation, the application of kinetic methods of trace analysis, particularly the catalytic variants, is now well established [6,7,8,9].…”
