By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Chromatography. According to news reporting originating in Durham, North Carolina, by NewsRx journalists, research stated, "Environmental vanadium contamination is a potential concern to public health, as evidenced by its place on the U.S. Environmental Protection Agency Drinking Water Contaminant Candidate List as a priority contaminant."
The news reporters obtained a quote from the research from RTI International, "Vanadium toxicity varies significantly between different oxidation states; therefore, it is crucial to be able to monitor the speciation of vanadium in environmental samples. In this study, a novel method is described that utilizes ion-pair reversed-phase ultra-high-performance liquid chromatography with inductively coupled plasma-sector field mass spectrometry (IP-RP-UHPLC-ICP-SFMS) to separate vanadyl and vanadate ions and resolve a major polyatomic spectral interference ((ClO+)-Cl-35-O-16) in less than a minute. Detection limits were obtained in the low ng L-1 (part per trillion) range with linear calibrations across several orders of magnitude (50 ng L-1-100 mu g L-1). The mechanism of chromatographic retention was elucidated through investigation of the role of ethylenediaminetetraacetic acid, tetrabutylammonium ion and pH on elution."
According to the news reporters, the research concluded: "The optimized method was then applied to the speciation of vanadium in local lake water samples."
