meta-Phosphoric acid

Application

• Impact of pH and application time of meta-phosphoric acid on resin-enamel and resin-dentin bonding.: This study examines the effects of varying pH levels and application durations of meta-phosphoric acid on the bonding properties between resin and dental tissues. Meta-phosphoric acid demonstrates varying efficacy in enhancing adhesive characteristics, crucial for dental restorations (Cardenas AFM et al., 2018).


• Dicalcium phosphate (CaHPO4·2H2O) precipitation through ortho- or meta-phosphoric acid-etching: effects on the durability and nanoleakage/ultra-morphology of resin-dentine interfaces.: This publication explores how ortho- and meta-phosphoric acid etching influences the precipitation of dicalcium phosphate in dental applications, particularly focusing on its impact on the durability of resin-dentine interfaces and potential implications for dental repair longevity (Feitosa VP et al., 2013).


• Simultaneous determination of ascorbic acid, aminothiols, and methionine in biological matrices using ion-pairing RP-HPLC coupled with electrochemical detector.: This study details a method leveraging reverse-phase high-performance liquid chromatography to analyze ascorbic acid alongside other compounds, with meta-phosphoric acid used to stabilize the samples during the analytical process, highlighting its application in precise biochemical measurements (Khan MI et al., 2011).


• Extraction, chemical characterization and biological activity determination of broccoli health promoting compounds.: This research utilized meta-phosphoric acid in the extraction processes for analyzing the chemical properties and biological activities of health-promoting compounds in broccoli, demonstrating the acid‚Ä≤s utility in food science and nutritional analysis (Ares AM et al., 2013).
