Ultrasensitive and selective determination of mercury in water, beverages and food samples by EDXRF and TXRF using graphene oxide modified with thiosemicarbazide

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

“…The work demonstrated that DSPME with TXRF spectrometry was a powerful combination for ultra-sensitive Hg detection in various samples across a range of concentrations. In the second study, 132 applied the DSPME method with thiosemicarbazide modified graphene oxide for selective Hg II separation, followed by measurement by both EDXRF and TXRF spectrometry. Following a similar approach to the first paper, the pre-concentration was optimised then validated with spiked samples (water, apple juice, beer, wine) and various reference materials (seawater, groundwater, wastewater, herring, cormorant and cod tissues, pig kidney, lobster, tobacco, scallion, celery, and spinach).…”
