Ultrasensitive determination and non-chromatographic speciation of inorganic arsenic in foods and water by photochemical vapor generation-ICPMS using CdS/MIL-100(Fe) as adsorbent and photocatalyst

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…8.1 Progress for individual elements 8.1.1 Arsenic. A useful non-chromatographic method for iAs determination was proposed by Wang et al 120 The team utilised CdS/MIL-100(Fe) as a sorbent and photocatalyst which allowed determination by PVG-ICP-MS. They synthesised the CdS/MIL-100(Fe) using previously described methods modied to establish optimal conditions.…”

“…This material acted both as adsorbent and photocatalyst. 120 The researchers showed that the As species could be separated on the basis of the kinetics of the reaction with the solid extractant: As V was absorbed and separated after 5 min, whereas As III was absorbed only after 105 min. The separated solid was resuspended in formic acid and the arsine generated on flow-through UV irradiation, swept via a GLS into an ICP mass spectrometer.…”

“…To date, various detection techniques have been successfully developed to determine inorganic arsenic, such as atomic absorption spectroscopy (AAS), 7 hydride generation atomic fluorescence spectrometry (HG-AFS), 8 anodic stripping voltammetry (SWASV-CV), 9 surface-enhanced Raman scattering, 10 and inductively coupled plasma mass spectrometry (ICP-MS). 11 Although these methods possess good sensitivity and high accuracy, they still appear to have some disadvantages, such as high cost, dependence on sophisticated equipment, time-consuming, and requirement of intricate sample pretreatment, which limit their extensive application.…”

“…Monitoring heavy metal pollution is crucial to managing it, and detection technology plays a key role in monitoring. Traditional methods for detecting Cd 2+ such as inductively coupled plasma mass spectrometry (ICPMS) (Wang et al, 2022), atomic emission spectrometry (AES) (Gondal et al, 2020), laserinduced breakdown spectrometry (LIBS) (Ren et al, 2022) and atomic absorption spectrometry (AAS) (Ibourki et al, 2021), have good detection performance and stability but are often complex, time-consuming, and require a large amount of reagents and complex instruments for sample pretreatment before on-line detection. Therefore, the development of new detection techniques that are fast, sensitive, speci c, and easy to operate is crucial to enhance the level of heavy metal pollution prevention and control, including Cd 2+ .…”
