“…e complexity of matrix and low concentration levels of palladium in industrials ( g g −1 ) and environmental (ng g −1 ) make direct measurements of this metal difficult. erefore, the application of highly sensitive techniques, such as ICP-MS [5][6][7] and GF AAS [8,9], coupled with a separation and enrichment procedure is necessary.…”

A simple, rapid, and powerful microextraction technique was used for determination of palladium (II) ion in water samples using dispersive liquid-liquid microextraction (DLLME) followed by graphite furnace atomic absorption spectrometry (GF AAS). e different variables affecting the complexation and extraction conditions such as extraction and disperser solvent type, extraction time, pH, and concentration of chelating agent were optimized. Under the optimum conditions, the calibration graph was linear in the ranges of 0.05-1 g L −1 with detection limit of 0.02 g L −1 . e precision (RSD %) for ten replicate determination at 0.2 g L −1 of palladium was better than 3.5% and the enrichment factor 166.5 was obtained from only 5.0 mL of sample. Under the presence of foreign ions, no signi�cant interference was observed. Finally, accuracy and application of the method were estimated by using test samples of natural waters spiked with different amounts of palladium.

“…Some GFAAS and ICP-MS methods for the determination of iron [9] and palladium [1,2,[10][11][12] in pharmaceutical products have been reported. The detection limits of these techniques are usually low enough for the determination of iron and palladium as limit tests in pharmaceutical samples.…”

Automated On‐Line Preconcentration of Palladium on Different Sorbents and its Determination in Environmental Samples

The determination of noble metals in environmental samples is of increasing importance. Palladium is often employed as a catalyst in chemical industry and is also used with platinum and rhodium in motor car catalytic converters which might cause environmental pollution problems. Two different sorbents for palladium preconcentration in different samples were investigated: silica gel functionalized with 1,5-bis(di-2-pyridyl)methylene tbiocarbohydrazide (DPTH-gel) and [1,5-Bis(2-pyridyl)-3-sulphophenyI methylene thiocarbonohydrazide (PSTH) immobilised on an anion-exchange resin (Dowex lx8-200)]. The sorbents were tested in a micro-column, placed in the auto-sampler arm, at the flow rate 2.8 mL min(-1). Elution was performed with 4 M HCl and 4 M HNO3, respectively. Satisfactory results were obtained for two sorbents.
