摘要: Here we have studied the complexation of naringin with Al(III) under physiological conditions (i.e., at 37 °C and in 0.16 mol L−1 NaCl). Solubility protonation constants ligand were first determined order to evaluate competition for H+ ions. Speciation analysis made by potentiometric titrations supported UV data shows that a occurs 1 : 1 ligand-to-Al(III) stoichiometric ratio. Notably, these combined mass spectrometry results indicate site is located on β-hydroxy ketone moiety.
