“…After the centrifugation, the organic phase was sedimented at the bottom of the centrifuge tube. The volume of final measurement solution was acquired approximately at 215 μ L. Then, a 50 μ L aliquot of this solution was rapidly introduced to the nebulizer of the flame atomic absorption spectrometer by using a microsyringe [ 43 – 45 ]. The bismuth signals were measured in the peak area mode utilizing the instrument software.…”

A dispersive liquid-liquid microextraction method for the determination of bismuth in various samples by flame atomic absorption spectrometry is described. In this method, crystal violet was used as counter positive ion for BiCl4 − complex ion, chloroform as extraction solvent, and ethanol as disperser solvent. The analytical parameters that may affect the extraction efficiency like acidity of sample, type and amount of extraction and disperser solvents, amount of ligand, and extraction time were studied in detail. The effect of interfering ions on the analyte recovery was also investigated. The calibration graph was linear in the range of 0.040–1.00 mg L−1 with detection limit of 4.0 μg L−1 (n = 13). The precision as relative standard deviation was 3% (n = 11, 0.20 mg L−1) and the enrichment factor was 74. The developed method was applied successfully for the determination of bismuth in various water, pharmaceutical, and cosmetic samples and the certified reference material (TMDA-64 lake water).

“…It has been reported that excessive palladium ions in environment will lead to health problems. Asthma, anaphylactic rhinitis, skin and eye irritations, degradation of DNA could be caused by palladium [13][14][15][16][17][18]. Hence, developing methods to detect, separate, and recover palladium from wastewater is of great importance in both scientific research and environment monitoring.…”

Fluorescent chemosensors based on silica nanoparticles and silicate glass slides were well designed and prepared. The as-prepared fluorescent silica particles and glass slides exhibited highly selective sensing and absorbing abilities to Pd 2? ions in aqueous phase. SiO 2 nanoparticles were first synthesized by the hydrolysis of tetraethyl orthosilicate (TEOS), and then -NH 2 groups were introduced to silica by treating with 3-aminopropyltriethoxysilane (APTES). Subsequently, 4-amino-1,8-naphthalic anhydride (ANA) was incorporated with the reaction of -NH 2 groups. Finally, salicylaldehyde (SA) was introduced by the reaction between amino groups in ANA and the -CHO groups in SA. Thus, the fluorescent silica nanoparticles were obtained. This method was expanded to prepare fluorescent silicate glass slides. Upon the addition of Pd 2? ions, the fluorescence quenched immediately. These chemosensors were selectively sensitive to Pd 2? ions as low as 10 lM. The absorption efficiency of fluorescent nanoparticles and glass slides for Pd 2? reached to 38.38 and 27.50 %, respectively. And the chemosensors also could be easily recycled and reused for at least five times. Fluorescent silica nanoparticles with only ANA or SA (not ANA and SA together) also exhibited the sensing ability to Pd 2? ions; however, it showed the shortage of Pd 2? ions selectivity. It suggested that it is necessary to introduce both ANA and SA for the high sensitivity and selectivity to Pd 2? ions.
