摘要:为了扩展造纸废液中的木质素磺酸钠的应用,以木质素磺酸钠和半胱氨酸为原料通过绿色的一步水热反应制备N, S双掺杂碳点,利用紫外可见光谱、荧光光谱和透射电镜等表征了碳点的光学性能、结构和对金属离子的选择性检测性能,结果表明制备的N,S双掺杂碳点可以识别Fe^3+,在0.5~100μmol·L^-1,Fe^3+的浓度与制备的碳点的荧光猝灭强度有良好的线性关系(R2=0.995)。将制备的碳点用于实际水样,结果表明可实现水样中3价铁离子的检测。此荧光探针原料成本低廉,制备绿色简便,在检测领域和生物质资源的高附加值应用领域有着很好的应用前景。
In order to expand the application of sodium lignosulfonate from pulping wastes, a green hydrothermal synthesis strategy was applied to synthesize nitrogen and sulfur co-doped carbon quantum dots using sodium lignosulfonate and L-cysteine. UV-vis spectroscopy, fluorescence spectroscopy and transmission electron microscopy were used to investigate optical properties, structure and metal ion selective detection of the carbon dots. The carbon dots can sensitively determine Fe^3+ with a good linear relationship in the range of 0.5~100 μmol·L^-1. The carbon dots were successfully used to measure Fe^3+ concentration in environmental water samples. Furthermore, this fluorescent probe has properties of low cost, simple and green preparation,which has good potential in metal ion detection and can increase biomass added values.
