“…The proposed extraction method has significant reproducibility and reliability by analysis GFAAS and UV-vis spectrometric methods. A high preconcentration factor and low LODs achieved in this work are comparable with literature reported works [4,21,[41][42][43][44][45][46][47][48][49] in Table 6. …”

A new solid phase extraction method using hair as a adsorbent has been developed for beryllium(II) prior to its spectrophotometric determination using chrome Azurol S. The effects of various variables such as pH, sample and eluent flow rates, eluent volume and concentration, sample volume, and interfering ions on the quantitative recoveries of beryllium(II) were investigated. The multivariate strategy was applied to screen out the multifactor and estimate the optimum values of experimental factors for the recovery of beryllium(II) using solid phase extraction. Calibration graph was linear in the range of 0.046-20 μg L −1 with correlation coefficient (r 2 = 0.987). The sensitivity (limit of detection (LOD)) and selectivity (preconcentration factor) of the proposed methods were 0.028 and 50, respectively. Validity and accuracy of the developed solid phase extraction method were checked by analysis of a certified reference water for Trace Elements (TM-28.3) and a real water samples by standard addition method, the relative recoveries >96% were obtained. The method was successfully applied for the determination of beryllium(II) in natural water samples.

“…Many methods for determination of a trace amount of Be have been reported: voltammetry, 3 spectrophotometry, [4][5][6][7][8] fluorimetry, [9][10][11][12] atomic absorption spectrometry (AAS), 11,[13][14][15][16][17][18] inductively coupled plasma atomic emission spectrometry (ICP-AES), 15 inductively coupled plasma mass spectrometry (ICP-MS), 19 and gas chromatography with electron capture detection (GC-ECD). 20 However, most of the above mentioned methods do not seem to satisfy the requirements for environmental monitoring of Be in the terms of facility, sensitivity, matrix toughness and cost-effectiveness.…”

A facile method has been developed for the highly sensitive and selective determination of ultratrace Be(II) ion using a new fluorimetric reagent, 10-hydroxybenzo[h]quinoline-7-sulfonate (HBQS), under extremely alkaline conditions, at pH 12.0. This reagent is quite suitable for the very small ion, Be(II), to form a 6-membered chelate ring, compatible with a high fluorescence yield. The stoichiometry of the chelate is 1:1 for Be-HBQS at pH 12.0. The calibration graph gave a wide linear dynamic range, 2-100 nmol dm(-3) of Be(II) ion with the detection limit (3s blank) of 0.52 nmol dm(-3), or 4.7 pg cm(-3). The excellent sensitivity and toughness toward the matrix influence were demonstrated using the artificial sample solutions for air-dust. Coupled with the simple masking procedure using EDTA, the method enables one to determine Be(II) ion at nanomolar levels in the presence of metals at the natural abundance levels in air-dust samples, typically Al, Ca, Cu, Fe, Mg, Pb, and Zn at 130, 150, 1.0, 70, 33, 3.0, and 8.0 micromol dm(-3), respectively, in the final solution. The proposed method was successfully applied to the determination of Be in urban air.
