Application


  • Interactions between irrigants commonly used in endodontic practice: a chemical analysis.: This study explores the chemical interactions between various endodontic irrigants, including phosphoric acid, when used in dental treatments. The findings highlight the potential effects of these interactions on the effectiveness of the treatments (Gomes BP et al., 2013).

  • Quantifying phosphoric acid in high-temperature polymer electrolyte fuel cell components by X-ray tomographic microscopy.: This research presents a method for quantifying phosphoric acid concentrations in fuel cell components using advanced X-ray imaging techniques, providing insights into the material characteristics and performance in high-temperature operational environments (Schmidt TJ et al., 2014).

  • Activated carbon fibers with a high heteroatom content by chemical activation of PBO with phosphoric acid.: The study discusses the production of activated carbon fibers using phosphoric acid, emphasizing the incorporation of heteroatoms that enhance the material′s adsorptive properties, relevant in various analytical applications in chemistry (Tascon JM et al., 2012).

  • Activated carbon fibers with a high content of surface functional groups by phosphoric acid activation of PPTA.: This article investigates the activation of poly(p-phenylene terephthalamide) with phosphoric acid to produce carbon fibers enriched with functional groups, enhancing their utility in chemical separations and catalysis (Tascon JM et al., 2011).

  • Phosphoric acid purification sludge: Potential in heavy metals and rare earth elements.: This research evaluates the potential of phosphoric acid sludge as a source of heavy metals and rare earth elements, offering a perspective on waste valorization and resource recovery in environmental chemistry (Moutte J et al., 2019).
