Abstract
An approach was developed to evaluate the mechanism involved, based on the interaction of rutin with an excess of metal chloride (magnesium, nickel or aluminum). It was found that the binding constants increased in the following order: 2.57 ± 0.23 × 104 L mol−1 for magnesium (II), 5.61 ± 0.45 × 107 L mol−1 for nickel (II) and 3.46 ± 0.16 × 109 L mol−1 for aluminum (III). The stoichiometric ratios (metal:rutin) were 1:1 for rutin and magnesium (II), 2:3 for rutin and nickel (II) and 1:2 for rutin and aluminum (III), determined by titration. This strategy allows the detection of aluminum ions in the presence of calcium, potassium, nickel and magnesium ions, demonstrating that this method provides a promising cationic sensor. So, these results open up a perspective for the study of the interaction mechanism of rutin and for the development of materials capable of capturing metal ions toxic through the construction of efficient bioinorganic systems.
