Tellurium Speciation Analysis of Soil Samples Taken from an Area Associated with the Storage, Processing, and Recovery of Electrowaste
( 16.06.2021 )
Polish researchers developed, optimized and validated a method for the determination of inorganic ionic Te(VI) and Te(IV) forms in easily-leached fractions of soil by Ion Chromatography-Inductively Co...

Speciation analysis of rhenium by capillary electrophoresis-inductively coupled plasma mass spectrometry
( 14.06.2021 )
A group of Chinese researchers developed a method for the speciation of rhenium using the hyphenated technique of capillary electrophoresis-inductively coupled plasma mass spectrometry. Since the rhen...

Speciation analysis of gadolinium retained in the rat brain after administration of gadolinium-based contrast agents
( 13.06.2021 )
A group of French researchers developed a method for enhancing the poor extraction of retained gadolinium from brain tissue. Subsequent analysis using size exclusion chromatography–inductively coupled...

Determination of the naturally occurring vanadium-complex amavadin in the fly agaric mushroom with HPLC-ICPMS
( 15.05.2021 )
Researchers from the University of Graz have developed a method to determine the vanadium-complex amavadin that occurs in the fly agaric mushroom. The method is based on high-performance liquid chroma...

Occurrence of Mercurous [Hg(I)] Species in Environmental Solid Matrices
( 11.05.2021 )
A group of Chinese researchers developed a mild extraction method that enabled them to catch the relatively unstable mercurous species from different environmental samples such as fly ash, soil, and p...
