“…The digestion process was continued for 45 min then the solution was prepared with 50 ml of distilled water (Kundu et al, 2018). The concentrations of arsenic were then measured by a flame atomic absorption spectroscopy at 197 nm (Farzana Akter et al, 2005;Mihucz et al, 2017).…”

Arsenic contamination is one of the major concerns today in Bangladesh. Various potential and threatening health risks for humankind could be occurred due to the consumption of Arsenic which has mixed with the food chain like fish and vegetables. Therefore, in this study, we analyzed 100 samples of deep tube well water, sediment, soil, vegetable, and fish samples, collected from five different Upazila of Joypurhat district in Bangladesh. The farming process, unplanned groundwater consumption, etc. could be marked as the main culprit for arsenic contamination in a region. However, Arsenic concentrations were determined by atomic absorption spectroscopy followed by the wet digestion method. From this analysis, a shocking result has been found that almost every sample contains arsenic and its level crossed the permissible limit set by WHO guidelines for water and food samples (vegetable and rice) which is an alarming issue for southeast Asian countries.

“…Extraction, adsorption, or preconcentration of the analyte of interest is another way to improve detectability. Several methods have been developed including the use of graphene oxide nanosheets for analysis of divalent metal ions and arsenic species, liquid-liquid microextraction for chromium speciation and selenium detection as well as preconcentration by means of co-deposition and microextraction to form complexes of rare earth elements [27][28][29][30][31][32][33]. Quantitative analysis of volatile elements like mercury has been achieved by complexation and oxidation [34].…”

Abstract Total reflection X-ray fluorescence (TXRF) spectrometry is a non-destructive and surface sensitive multi-element analytical method based on energy dispersive X-ray fluorescence spectrometry with detection limits in the lower picogram range. It utilizes the total reflection of the primary X-ray beam at or below the critical angle of incidence. At this angle, the fluorescence intensity is substantially enhanced for samples present as small granular residue or as thin homogenous layer deposited at the surface of a thick substrate. Generally, two types of application exist: micro- and trace-analysis as well as surface and thin-layer analysis. For micro- and trace-analysis, a small amount of the solid or liquid sample is deposited on an optically flat substrate, typically quartz or polycarbonate. The dried residue is analyzed at a fixed angle setting slightly below the critical angle. Quantification is carried out by means of internal standardization. For surface and thin-layer analysis, the surface of an optically flat substrate is scanned. Variations of the incident angle of the primary X-ray beam provide information about the type and sometimes also the amount of material present at or slightly below the surface of the substrate. Major fields of application are environmental samples, biological tissues, objects of cultural heritage, semiconductors and thin-layered materials and films.

“…Accordingly, a suitable preconcentration step prior to instrument detection is necessary. For the extraction of arsenic in different samples, a variety of methods have been used so far, including liquid-liquid extraction (LLE), 21 solid phase extraction (SPE), 22,23 cloud point extraction (CPE), 24 solid-phase microextraction, 25,26 dispersive liquid-liquid microextraction (DLLME) [27][28][29] and dispersive liquid-liquid microextraction based on solidication of a oating organic drop (DLLME-SFO). [30][31][32] Advantages and disadvantages of these techniques have already been discussed.…”
