Determination of beryllium in plants by means of flameless atomic absorption with zirconium-coated and non-coated graphite tubes

Complexation of Be(II) Ion with 1-(2,4-Dihydroxy-1-phenylazo)-8-hydroxy-3,6-naphthalenedisulfonate as the Chemical Basis of the Selective Detection of Ultratrace Be by Reversed-Phase High-Performance Liquid Chromatography

“…The detection limit reported here is a little greater than that reported for ICPMS (2.2 pg/mL) and still comparable with that of GC-EC measurements − It is stressed that the addition of reagent in an eluent which gives rise to the undesirable background fluctuation seriously decreases the chance of access to the potentially low detection limit obtained with modern absorbance detectors.…”

“…While beryllium and its compounds are very important and useful in industry, they are very harmful, with tumor-promoting properties . Many methods for Be determination have been reported: fluorometry, spectrophotometry, , voltammetry, atomic absorption spectrometry (AAS), − and gas chromatography with electron capture (EC) detection . Most of the above methods, however, do not seem to have sufficient compatibility in terms of sensitivity and accuracy; separation stages such as adsorption and solvent extraction are most often necessary to guarantee accuracy for the ppt to sub-ppb range of Be in the presence of complicated matrixes.…”

Quantifying beryllium concentrations in plant shoots from forest ecosystems using cation‐exchange chromatography and quadrupole ICP‐MS

“…An alternative Be separation scheme frequently used for separation of very small amounts of cosmogenic 10 Be uses oxalic acid and 0.5 M HCl (or alternatively 1 M HNO 3 ) instead of 0.3 M HNO 3 and 0.3 M HF to separate Be from matrix elements. 55 This method was designed for rocks, minerals, and water samples and has the advantage that trivalent cations such as Fe 3+ , Al 3+ , and Ti 3+ are eluted first as metal oxalates while Be is TA B L E 3 Instrumental operating parameters for 9 Be analyses with Q-ICP-MS (iCAP, Thermo Fischer Scientific) 9 Be, 27 Al, 48 Ti, 13 C, ( 103 Rh) retained and separated from Na and K with 0.5 M HCl. However, a non-negligible fraction of the Mg elution peak, and small fractions of the K and Ca peak overlap with the Be peak (later separated by hydroxide precipitation).…”

“…Beryllium concentrations of non-woody foliage and grass fall into the concentration range of 1.3 to 2000 ng/g previously found in non-crop plants and surveyed from literature. 1,3,[6][7][8][9][10][11][12][13][14][15] Woody foliage often falls below this concentration range.…”

“…This method achieved a limit of detection of 1.5 ng/g. 9 Finally, a two-step ion chromatography method was developed by Hayashibe et al 38 to eliminate spectral interferences during analysis by AAS. In this method, Be is purified in biological material from matrix elements by using cationexchange resin (BioRad TM AG R 50W-X8, 100-200 mesh) in hydrogen form and anion-exchange resin (BioRad TM AG R 1-X8, 100-200 mesh) in chloride form.…”
