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.

“…[1][2][3][4][5][6][7][8][9] A liquid electrode plasma (LEP), which is generated by applying a voltage pulse in an aqueous sample solution injected in a small cuvette, allows one to excite the elements, and the emission spectra derived from the elements in the sample solution are observed in the plasma. [5][6][7][8][9] An elemental analyzer based on LEP-AES is commercially available; 8,9 it is small enough to be portable. Since neither high-purity gas nor a large amount of electricity is required for LEP-AES, the cost for the measurement is much lower than those in ICP-AES.…”

“…Another feature is that the volume of sample solution required for the measurement is less than 0.1 mL. [7][8][9] LEP-AES has been applied to determine sodium and lithium in zirconium dioxide 7 and lead in soil. 9 In LEP-AES, however, the emission intensity is significantly influenced by the matrices in sample solution; this often affects the accuracy and precision in the determination.…”

“…[10][11][12][13] In LEP-AES determination, only the solid phase extraction using Meta SEP AnaLig PB-01 was applied to the separation/preconcentration of lead in the soil-extracted solution. 9 We previously reported that a chelate resin immobilizing carboxymethylated pentaethylenehexamine (CM-PEHA resin) is excellent for separation/preconcentration of trace elements in water samples. 14 In the solid phase extraction using CM-PEHA resin, many elements including vanadium, manganese, iron, cobalt, nickel, copper, zinc, molybdenum, cadmium, and lead were efficiently extracted over a wide pH range, whereas alkaline elements such as sodium and potassium were not extracted and magnesium and calcium were scarcely recovered at pH below 7.…”
