- Abstract:以抗坏血酸(AA)为碳源,通过一步水热法合成水溶性绿色荧光碳纳米点(Carbon nanodots,CDs)。采用透射电子显微镜(TEM)、X射线光电子能谱(XPS)、傅里叶变换红外光谱(FTIR)、紫外-可见吸收光谱(UV-vis)和荧光光谱对其形貌和性质进行了研究。基于此碳纳米点与Al 3+ 结合产生的荧光增强现象,建立了检测Al 3+ 的荧光分析方法,在50~500 nmol/L(R 2 =0.9988)和500~2000 nmol/L(R 2 =0.9976)范围内呈良好的线性关系,检出限为10.23 nmol/L (S/N=3),并用于对瓶装饮用水样品中Al 3+ 的检测。
