Application


  • Preconcentration of molybdenum, antimony and vanadium in gasoline samples using Dowex 1-x8 resin and their determination with inductively coupled plasma-optical emission spectrometry.: This study demonstrates the efficiency of Dowex 1-X8 ion-exchange resin in the preconcentration of trace metals from complex matrices, facilitating their quantification via ICP-OES, a technique pivotal for ensuring fuel quality and compliance with environmental regulations (Nomngongo et al., 2013).

  • Anion-exchange chromatographic separation of Hg for isotope ratio measurements by multicollector ICPMS.: Explores the use of Dowex 1-X8 for the chromatographic separation of mercury isotopes, enhancing the precision of isotope ratio analysis which is crucial in geochemical and environmental studies (Malinovsky et al., 2008).

  • Uranium removal from contaminated groundwater by synthetic resins.: Discusses the application of Dowex 1-X8 in the removal of uranium from water sources, highlighting its potential in remediation efforts at sites affected by radioactive contamination (Phillips et al., 2008).

  • Selective colorimetric determination of TNT partitioned between an alkaline solution and a strongly basic Dowex 1-X8 anion exchanger.: Presents a novel approach for the detection of trinitrotoluene (TNT) using Dowex 1-X8, which could be employed in forensic science to improve the sensitivity and selectivity of explosive residue analysis (Uzer et al., 2008).

  • Fluidized beds in flow analysis: use with ion-exchange separation for spectrophotometric determination of zinc in plant digests.: Showcases the integration of Dowex 1-X8 in flow analysis systems for the efficient separation and subsequent spectrophotometric determination of zinc, essential for agricultural and nutritional research (Ribeiro et al., 2006).
