may alter the analysis and cause interference, lowering the efficiency of the analytical methods [12; 19]. Extraction and preconcentration via various methods, such as solid-phase extraction or dispersive liquid microextraction, enhance the isolation of a matrix and increase the concentration of the analyte [19; 20; 21; 22; 23; 24]. For example, [PERSON] et al. [25] determined arsenic via on-line preconcentration and reported limits of detection and quantification of 0.02 and 0.07 \(\mathrm{\SIUnitSymbolMicro\text{g}}\) L\({}^{-1}\), respectively. [PERSON] et al. [26] conducted a comparison between different extraction methods, Tessier, Rauret and Shiowatana, and reported that Shiowatana is the best procedure for arsenic extraction. [PERSON] et al. [27] identified the solid-phase sources and geochemical mechanisms of the release of arsenic, and their results confirmed that the glacial sediments at the interfaces between aquifers and aquitards are geochemically active zones for arsenic. [PERSON] et al. [28] used magnetic ferrite particles to study low concentrations of arsenic and reported a limit of detection of 0.02 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):L\({}^{-1}\) of arsenic for a sample volume of 10 mL. [PERSON] et al. [29] applied a highly selective determination for an arsenic analysis, and the detection limit was 0.045 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):m\(\cdot\)L\({}^{-1}\). In addition, the process can be successfully applied for the analysis of high-salinity water. [PERSON] et al. [30] used magnetic materials for the extraction of arsenic ions from contaminated aqueous streams, which proved to be effective and beneficial for the separation of the toxic arsenic ions, and demonstrated a process for efficient practical applications. [PERSON] and [PERSON] [31] developed a simple and efficient method using dual-cloud point extraction (dual-CPE) with a detection limit for As(III) of 0.72 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):mL\({}^{-1}\). [PERSON] et al. [32] applied a method for arsenic speciation analysis based on a paper-based analytical device. The proposed method showed limits of detection and quantification of 1.1 and 3.6 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):mL\({}^{-1}\), respectively. [PERSON] et al. [33] prepared magnetic \(\mathrm{Fe}_{3}\mathrm{O}_{4}\) nanocomposites to be applied in the preconcentration of arsenic, and under optimized conditions, the limits of detection and quantification were 8.6 and 28.5 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):L\({}^{-1}\), respectively. [PERSON] et al. [34] used on-line sample preconcentration techniques and reported limits of detection in the range of 0.08-0.3 ppb for arsenic. [PERSON] et al. [35] prepared a novel nanocomposite suitable for the sorption of selected species of arsenic and chromium and indicated a limit of detection of 0.02 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):mL\({}^{-1}\) for arsenic and a limit of detection of 0.11 \(\mathrm{\SIUnitSymbolMicro\text{g}}\):mL\({}^{-1}\) for chromium. Solid-phase microextraction is preferred for sample purification due to its high efficiency in preconcentrating a wide range of pollutants, as well as the high sample volume that can be applied. The key to this technique is the preparation of suitable and superior adsorbent materials that exhibit the desired levels of porosity, dispersibility and stability [36; 37; 38; 39]. The development of an efficient adsorbent is the key to applicable and effective separation, even for extraction and/or adsorptive wastewater treatments [40; 41]. Nowadays, metal-organic-framework-based adsorbents have a magic ability to adsorb and separate materials for many purposes such as catalysis, energy and extraction techniques [42; 43; 44; 45; 46; 47]. These categories of materials are constructed using inorganic parts, which may be metal oxide clusters and/or metal ions, which are able to co-ordinate an organic ligand moiety.
