“…It is reported in the literature that the extraction yield for DVB/CAR/PDMS fibers is much higher than that observed with PDMS fibers in the extraction of organometallic compounds of mercury, lead, and tin [29]. Extraction of the analyte in the case of in-tube SPME involves the washing of the capillary with the sample solution by applying , draw from the sample-eject into the sample' extraction cycles.…”

“…Polydimethylsiloxane is the most useful liquid type coating. It has been used in various applications of SPME to the analysis of organometallic species (see Table 1 [26,27], polydimethylsiloxane/divinylbenzene (PDMS/DVB) [26,28], divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) [29], carbowax/polydimethylsiloxane (CW/PDMS) [24], and polyacrylate (PA) [28].…”

Applications of solid phase microextraction for the determination of metallic and organometallic speciesThis paper reviews recent developments of solid phase microextraction (SPME) and its application to the analysis of organometallic species of lead, arsenic, mercury, tin, and selenium by hyphenation with HPLC-GC-atomic spectrometry. In the first part, a background of the technique is given in terms of derivatization, fibers used, extraction and desorption conditions. The second part summarizes typical SPME applications to the determination of organometallic species and the main experimental conditions with the aid of specific examples. Most of the applications comprise alkylation with NaBEt 4 and headspace extraction followed by gas chromatographic separation with a suitable detector.

“…[111,112]. Laboratory studies revealed, urine specimens were analyzed for inorganic mercury using an automated flow injection mercury system (FIMS) that uses cold vapor atomic absorption spectrometry and Urine specimens were analyzed for total mercury using inductively coupled plasma mass spectrometry (ICP-MS) [113][114][115]. CVG technique has some merits such as high sensitivity, wide linear dynamic range, low noise level, fast analysis speed, ease of operation, and low cost [116].…”

Objective: This paper mainly discusses and summarises the potential issues of pollution caused by the Mineral elements, Mercury, Lead and Arsenic, its possible impacts on the human beings and the suggested solutions. Methods: This paper is prepared by reviewing the latest academic literatures. Result: First, this article discusses two aspects including the effects of Mercury, Lead and Arsenic on the Chinese herbal medicine and the potential issues of causing the environmental pollution. And then further study its toxicity effects and the side impacts on the human bodies in order to realize the actual circumstances people are encountering nowadays. This paper will also the corresponding its treatment method of reviews. Hope this will provide a valuable reference. Conclusion: Theses issues caused by the Mineral elements are prominent nowadays, thus the ongoing researches on the impacts of pollution and the possible solutions are regarded as highly valued in order to conserve the natural environment and meanwhile safeguard the well beings of people and the future offspring.

“…7,8 Solid phase microextraction (SPME) 9 and solvent microextraction (SME) 10,11 have been widely used in recent years as powerful tools for the preconcentration and matrix separation of a variety of organic and inorganic compounds. SPME [12][13][14][15][16][17] and headsapace (HS)-SME 18 of tin have been often used in combination with a chromatographic separation step for tin speciation. Alternatively, direct coupling of a microextraction technique with a sensitive atomic spectroscopy method can lead to lower detection limits and faster tin determinations with substantially simpler and cheaper devices.…”

O estudo introduz um método para microextração por headspace (HS-SME) de hidreto de estanho em uma microgota aquosa contendo Pd(II) e tributil fosfato (TBP) como uma estratégia de enriquecimento e de modificação de matriz previamente à determinação por ETAAS. O hidreto de estanho foi gerado pela adição de um volume fixo de solução de borohidreto de sódio na amostra. Os efeitos de vários parâmetros, tais como volume da amostra, quantidade de NaBH 4 , Pd(II) e TBP na gota, tipo de ácido e concentração na amostra, tempo de extração e volume da gota, foram cuidadosamente estudados. Possíveis interferências causadas por concomitantes foram testadas e nenhum efeito significativo foi gerado por hidretos formados por outros elementos. Concentrações salinas de até 0,3 mol L -1 foram toleradas pelo método HS-SME, porém aumentos drásticos nos sinais de absorbância e de fundo ocorreram em um método de injeção direta. O HS-SME mostrou-se um método sensível para determinação de estanho com um limite de detecção de 2,09 ng mL -1 e uma precisão melhor do que 4,04% (RSD). O método foi aplicado com sucesso para a determinação de estanho em águas residuais e suspensões.The study introduces a method for headspace solvent microextraction (HS-SME) of tin hydride into an aqueous microdrop containing Pd(II) and tributyl phosphate (TBP) as an enrichment and matrix modification method prior to ETAAS determination. The tin hydride was generated by injection of a fixed volume of sodium tetrahydroborate solution into the sample. Effects of several parameters including sample volume, amount of added NaBH 4 , Pd(II) and TBP concentrations in the drop, acid type and concentration in the sample, extraction time and drop volume were carefully studied. Possible interferences from a number of elements were tested and no significant interference from hydrides of other elements was observed. Salt concentrations up to 0.3 mol L -1 was tolerated by the HS-SME method while it drastically increased the background and signal absorbances in a direct injection method. The HS-SME resulted in a relatively sensitive tin determination method with a detection limit of 2.09 ng mL -1 and a precision better than 4.04% (RSD). The method was successfully applied to the determination of tin in waste water and slurry samples.
