“…Solid phase extraction has been demonstrated to be a highly effective preconcentration method when first applied to spectrometric determination [14,19,20]. Among the different sorbents that were tested for this enrichment stage are resins such as polyacrylacylaminothiourea [21], imidazoline [22], Metalfix-Chelamine [23,24], Amberlite XAD-16 [25], Amberlite XAD-7 [26], Dowex 1-X10 [27], Polyorgs 17 [28], HHY-10A macropore anion resin [29], activated alumina [30] and modified silica gels like silica gel functionalized with 1,5-bis(di-2-pyridyl)methylene thiocarbohydrazide [31], modified silicagel SeparonTM SGX [32], silica gel modified with propylamine groups [33]. Very good sorption properties of this last resin led us to choose it for the present study.…”

A solid phase extraction technique for the determination of platinum(IV) at trace levels by inductively coupled plasma mass spectromA solid phase extraction technique for the determination of platinum(IV) at trace levels by inductively coupled plasma mass spectrometry (ICP-MS) was developed. The method was based on retention of platinum in a sample on silica gel modified with aminepropyl groups. The retention of platinum(IV) from the sample solution and the recovery of platinum with 1.0 mol L−1 thiourea solution were quantitative. The relative standard deviation (RSD) was calculated as 5% (n = 7) at the 10 ng L−1 level. The enrichment factor was found to be (50-fold) for 250 mL of water sample. Under optimum conditions, the method detection limit (MDL) was found to be 1 ng L−1 for platinum in water matrices. Recoveries of Pt from spike addition to atmospheric water samples were quantitative (80–95%). The present method was used for the determination of platinum in precipitation, throughfall and runoff water samples.

“…3 Thus, alkali fusion provides soluble salts of most of geological materials. [23][24][25] Dry ashing followed by dissolution of the residue with acids is often used for the digestion of biological, environmental and clinical samples. [26][27][28] Acid dissolution is extensively used for the digestion of different matrices, and can be carried out in open or closed systems, such as high-pressure ashers (HPA) [29][30][31] or high-pressure vessels heated by microwaves.…”

Trends in Sorption Preconcentration Combined with Noble Metal Determination

Nowadays much attention is being paid to the determination of trace amounts of noble metals in geological, industrial, biological and environmental samples. The most promising techniques, such as inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS) and electrothermal atomic absorption spectrometry (ETAAS) are characterized by high sensitivity. However, the accurate determination of trace noble metals has been limited by numerous interferences generated from the presence of matrix elements. To decrease, or eliminate, these interferences, the sorption preconcentration of noble metals is often used prior to their instrumental detection. A great number of hyphenated methods of noble metal determination using sorption preconcentration have been developed. This review describes the basic types of available sorbents, preconcentration procedures and preparations of the sorbent to the subsequent determination of noble metals. The specific features of instrumental techniques and examples of ETAAS, FAAS, ICP-AES, ICP-MS determinations after the sorption preconcentration of noble metals are considered. The references cited here were selected mostly from the period 1996 -2006.

“…However, there is no role of palladium in any biological processes and all palladium compounds are known to be highly toxic and carcinogenic [1][2][3]. Due to its economical and environmental importance, there is a necessity to determine trace concentration of palladium in environmental samples by highly sensitive analytical techniques, such as flame atomic absorption spectrometry (FAAS) [4][5][6], graphite furnace atomic absorption spectrometry [7,8], highperformance liquid chromatography [9], inductively coupled plasma atomic emission spectrometry (ICP-OES) [10][11][12], and inductively coupled plasma mass spectrometry [13].…”

In the proposed approach, a simple and efficient ultrasonication ionic liquid-based dispersive liquid-liquid microextraction (UIL-DLLME) was described. Microsampler system-assisted flame atomic absorption spectrometer was used at the determination step of Pd(II). 1-Phenylthiosemicarbazide (PTC) and 1-hexyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide [C 6 mim][Tf 2 N] were used as the chelating agent and the extraction solvent of UIL-DLLME, respectively. Ultrasonication was used for dispersing of [C 6 mim] [TF 2 N] into samples. Different experimental conditions affecting UIL-DLLME of Pd(II) were examined and optimized. The analytical performance characteristics of investigated method including limit of quantification (33 μg L −1 ), limit of detection (11 μg L −1 ), relative standard deviation (% 3.1), linear range (33-500 μg L −1 ), and enrichment factor (52) were calculated. The optimized UIL-DLLME was applied to different water samples.
