基于层状二硫化钼纳米片比色检测亚锡离子
|
摘要
在醋酸/醋酸钠缓冲溶液(pH=4.5)中,亚锡离子对层状二硫化钼(MoS_2)纳米片催化过氧化氢(H_2O_2)氧化邻苯二胺(OPD)的显色反应有很强的抑制作用,据此构建了一种检测亚锡离子的比色传感器.实验结果表明,与不加Mo S2纳米片的OPD/H_2O_2比色传感体系相比,MoS_2/OPD/H_2O_2体系检测亚锡离子的灵敏度显著提高,线性范围变宽.在优化的条件下,MoS_2/OPD/H_2O_2传感体系检测亚锡离子的线性范围为0.02~3.0μmol/L,检出限为8 nmol/L(S/N=3).该传感体系对检测亚锡离子具有高的选择性,可用于湖水中亚锡离子的检测.
In acetate / sodium acetate buffer( pH = 4. 5),tin( Ⅱ) ion displayed strong inhibitory effect on the color reaction of o-phenylendiamine( OPD) oxidized by hydrogen peroxide( H_2O_2) in the presence of layered molybdenum disulfide( MoS_2) nanosheets-based catalysts. This phenomenon was exploited to develop a colorimetric sensor for detection of tin( Ⅱ) ions. The experimental results showed that compared with the OPD /H_2O_2 colorimetric sensory system without Mo S2 nanosheets,MoS_2/ OPD / H_2O_2 colorimetric sensory system exhibited increased sensitivity,low detection limit,and wide linear range toward tin( Ⅱ) ions. Under the optimum experimental conditions,the tin( Ⅱ) sensor based on MoS_2/ OPD / H_2O_2 system provided a linear range of 0. 02—3. 0 μmol / L with a low detection limit of 8 nmol / L( S / N = 3). Moreover,the MoS_2/ OPD /H_2O_2 system displayed a high selectivity for tin( Ⅱ) detection,and can be used for the detection of tin( Ⅱ)ions in lake water samples.
