“…The speciation analysis of As(III) and As(V) in tap water, lake water, and river water samples collected from local sources was carried out with recoveries >98.7%. 47 Tunçeli et al 48 proposed a SPE method using Amberlite IRA 900 resin as an adsorbent for the speciation of As(III) and As(V) and total As. ETAAS with Ni chemical modifier was used for detection.…”

Considerable interest is continuing to be shown in the speciation of metals, metalloids, and organometals due to the dependence of their toxicity and mobility on their chemical form. This review focuses on the speciation analysis of metals, metalloids, and organometals by solid phase extraction before spectrometric detection, and all aspects of analytical speciation such as determination of oxidation states and organometallic compounds. Some applications of speciation of metals and metalloids are also presented and discussed in this review. Fractionation, which is used sometimes as speciation, and chromatographic detection are not discussed. This review covers approximately the last four years ( -March 2016, offering a critical review of the speciation of metals, metalloids, and organometals.

“…A macrocycle-immobilised SPE system, commonly known as molecular recognition technology (MRT) gel, has also been used to selectively separate As III and As V in aqueous matrix. 73 The As species in solution (or in the eluent) were subsequently quan-tied with ET-AAS. It was found that As V can be selectively collected on the SPE system within the range of pH 4 to 9, while As III was passed through the MRT-SPE.…”

“…A simple flow-based method was also developed for the discerning separation of triand pentavalent arsenic species from aqueous matrix using another macrocycle-immobilized SPE, specifically AnaLig An-02 [142]. The selectivity characteristics of AnaLig TE-01 towards arsenic [141] and iron-species [143] were further employed to formulate an approach for the treatment of spent iron-oxide coated sand from filters used in arsenic removal [144].…”

Microchemical Journal, 110: 485-493, 2013 The original publication is available at: http://dx.doi. org/10.1016/j.microc.2013.06.006 Abstract Solid-phase extraction (SPE) approach was introduced approximately five decades ago, and until then development of SPE materials is seamlessly continued. Lately, the SPE-based research is increasingly focused in developing more explicit materials to achieve meticulous separation of elements from complex solution matrices with high concentrations of interfering ions. One group of SPE materials includes those with macrocyclic ligands immobilized on a solid-phase, which are capable of selective separation and preconcentration of elements, and such selectivity in metal retention is generally termed as molecular recognition. In the process, the designed 'host' material possesses a high degree of recognition to specific elements or groups of elements called 'guest', and the recognition capability remains effective at the very low concentrations of the 'guest' species or when those present in complex matrices. The routes to the development of element-selective SPEs, the operating principles, applications and limitations are discussed in this review.

The growing extent of metal pollution also initiated a number of legislative measures, such as, RoHS or ELV directive has been imposed to specify the limit of trace elements in the industrial products, while the EU directive defined the acceptable concentrations of different elements in cultivable soils.Sensitive analytical techniques such as, flame atomic absorption spectrometry, electrothermal atomic absorption spectrometry, inductively coupled plasma mass spectrometry, inductively coupled plasma optical emission spectrometry, and so forth are available for precise analysis of trace elements in solution. An overall analytical process comprises a number of succeeding steps, including sampling, sample preparation, separation and quantification. Among the aforementioned steps, sample preparation is by far the most important error source in modern analytical method development due to the low species concentration or heterogeneous distribution of the analytes in the matrix as well as the complex nature of the sample matrices. Therefore, a clean-up/separation step is often recommended before the analytical determination of trace elements in effluent or industrial waste waters to avoid the interfering effect from the matrix ions or to facilitate preconcentration due to their low concentrations in samples.
