“…Because of this, separation and/or preconcentration steps should be applied before the detection step of elements by FAAS. 9 Several separation and preconcentration methods have been used for the Mn 2+ detection, such as cloud-point extraction (CPE), 10 liquid-liquid microextraction (DLLME), 11 and solid-phase extraction (SPE). 12 Among them, SPE is the most common method as the separation and preconcentration of elements by researchers, owing to the high enrichment factor, the ability to combine with different detection techniques, low cost and low consumption of organic solvents.…”

“…[2][3][4] Flame atomic absorption spectrometry (FAAS) is relatively simple and available technique in many laboratories for heavy metal determination. [5][6][7][8][9][10] Because of the large amount of organic substances in the samples, digestion or ashing is required prior to analysis and the low concentrations of the measured elements demand well-organized [11]. Interest in human hair as a clinical sample has increased in recent years due to certain advantages offered by human hair over other clinical specimens such as blood or urine samples.…”

“…Various SPE materials which have been used for the preconcentration of trace metal ions as their chelates include, activated silica gel [40,41], carbon [42][43][44][45], polyurethane foam [46] microcrystalline naphthalene [47], C 18 cartridges [48], Chelex-100 [49], Alumina [50], functionalized polyurethane foam [51], modified silica [52,53], sulfur powder [54] and Amberlite XAD resins [55][56][57][58][59][60][61]. Amberlite XAD (styrene-divinyl benzene copolymer) resins, as the copolymer backbone for the immobilization of chelating ligands, have some physical superiority, such as porosity, uniform pore size distribution, high surface area, and chemical stability toward acids, bases, and oxidizing agents, as compared to other resins [62][63][64][65].…”
