摘要
基于芦丁与过量氯金属(镁、镍或铝)的相互作用,开发了一种方法来评估所涉及的机制。发现绑定常量增加按照以下顺序: 2.57±0.23 × 104 L 摩尔−1镁(II), 5.61 ±0.45 × 107 L 摩尔−1 镍(II)和3.46±0.16 × 109 L 摩尔−1铝(III),化学计量比(金属:芦丁)1:1芦丁和镁(II), 2:3芦丁和镍(II)和1:2芦丁和铝(III),由滴定。该策略允许在钙、钾、镍和镁离子存在的情况下检测铝离子,表明该方法提供了一种有前途的阳离子传感器。因此,这些结果为研究芦丁的相互作用机制以及通过构建高效的生物无机系统开发能够捕获有毒金属离子的材料开辟了一个新的视角。
Fast determination of rutin-metal binding constants: A way to metal detection at the environment
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.
