Determination of trace tellurium by photochemical vapor generation-atomic fluorescence spectrometry using bifunctional Co-MOF-74 for preconcentration and sensitization

Yuheng Lu et al.

Summary: The highly sensitive detection of trace tellurium (Te(IV)) in real samples with complicated matrix was achieved by using a new method based on photochemical vapor generation-atomic fluorescence spectrometry (PVG-AFS) and Co-MOF-74 as an adsorbent and Co2+ ion sensitizer. The synthesized Co-MOF-74 showed excellent adsorption capability for Te(IV) within a short time. After conversion to volatile compounds under UV irradiation, the Te(IV) was detected by AFS. The proposed method exhibited a limit of detection of 0.08 ng/mL for Te(IV) after a 50-fold preconcentration and was successfully applied to the analysis of various natural water samples with satisfactory spike recoveries.

Highly Efficient Photochemical Vapor Generation for Sensitive Determination of Iridium by Inductively Coupled Plasma Mass Spectrometry

Stanislav Musil et al.

Summary: In this study, a highly efficient photochemical vapor generation (PVG) method was described for generating a volatile species of Ir for subsequent detection. PVG efficiency was optimized by adjusting irradiation time, pH of the reaction medium, and the presence of metal sensitizers. The developed methodology showed high repeatability and low limits of detection for Ir analysis by ICPMS. Interference from various substances was investigated, and the method showed excellent tolerance towards chloride. The practical application of the method was demonstrated by direct analysis of water samples with high spike recovery.

Qing Yang et al.

Summary: Efficient simultaneous photochemical vapor generation (PVG) of ruthenium (Ru) and osmium (Os) in formic acid medium was demonstrated, with impressive limits of detection achieved for both elements. The synergistic enhancement from cobalt and cadmium ions on PVG efficiency was discovered, and the accuracy of the proposed PVG-ICP-MS method was validated through analysis of water samples. Additionally, volatile compounds of Ru were trapped and generation of Ru carbonyls was verified by high-resolution ESI-MS.

Summary: The volatile synthetic products of photochemical vapor generation of Os(iv) and W(vi) have been confirmed by GC-MS. Osmium tetroxide and tungsten hexacarbonyl were identified as the species generated in different oxidizing and reducing media. However, the PVG products of Os and Ru generated in reducing media could not be determined using GC-MS and require other more direct methods for analysis.

Summary: The PVG of Ni in fresh water samples was optimized for high sensitivity and low LOD using a flow-through photoreactor with 30% formic acid, achieving an overall efficiency of 42% and LOD of 1.9 ng L-1. The addition of 1.5 M ammonium formate improved efficiency, but did not significantly impact analytical performance. Interferences from inorganic anions and transition metals were investigated, and accuracy was confirmed through analysis of standard reference materials.

One Fe3O4, two birds: Preconcentration and enhanced photochemical vapor generation for the determination of bismuth by atomic fluorescence spectrometry

Lanlan Li et al.

Summary: In this study, Fe3O4 served as both an adsorbent and photocatalyst in the photochemical vapor generation-atomic fluorescence spectrometry (PVG-AFS) determination of Bi(III) after preconcentration. The effects of formic and acetic acid concentration, UV irradiation time, Fe3O4 concentration, and interferences from co-existing ions were investigated. Results showed that the AFS intensity was slightly enhanced by the mixed acid solution, but a significant enhancement was observed when Fe3O4 was used as a photocatalyst. Fe3O4 can decompose in the mixed acid solution, generating Fe3+ which acts as a sensitizer for improving Bi(III) efficiency. Under optimized conditions, the LOD of the proposed PVG-AFS system with or without preconcentration (5 mL sample) were 0.44 ng/mL and 0.07 ng/mL, respectively. The PVG-AFS system was successfully applied to the determination of water samples and demonstrated good accuracy and applicability with recoveries ranging from 94% to 104%.
