Collaborative determination of trace element mass fractions and isotope ratios in AQUA-1 drinking water certified reference material. | LitMetric

AI Article Synopsis

  • The Isotrace CNRS workgroup and the National Research Council of Canada have identified new trace elements and isotopic ratios in AQUA-1 drinking water that were not previously certified.
  • They analyzed SLRS-6 river water for quality control and comparison with AQUA-1, as both were sampled from the same area but treated differently.
  • The study provides mass fractions for multiple elements and isotopic ratios for strontium and lead, using ICP-MS techniques, with data categorized as consensus or indicative based on availability and uncertainty.

Article Abstract

The Isotrace CNRS workgroup in collaboration with National Research Council of Canada has characterized a number of trace element mass fractions and isotope ratios currently not certified in AQUA-1 natural drinking water reference material (NRC Canada). This survey further expands the use of this material as a tool for environmental quality control, method validation, and method development tool for the international community. Simultaneously, the SLRS-6 river water was analyzed as quality control and also in order to compare both water characteristics, which were sampled in the same area but having undergone different treatment. Mass fractions for B, Cs, Li, Ga, Ge, Hf, Nb, P, Rb, Rh, Re, S, Sc, Se, Si, Sn, Th, Ti, Tl, W, Y, Zr, REEs, and six isotopic ratios are proposed for Sr and Pb. Measurements were mostly performed using ICP-MS with various calibration approaches. The results are reported as consensus or indicative values depending on the number of available datasets, with their associated uncertainties.
