摘　　要：以豇豆为碳源通过一步水热合成法制备新型的荧光碳量子点。以荧光强度为指标,通过单因素和正交试验探究了温度、时间、质量及溶剂等影响因素对制备的影响,确定碳量子点最佳制备条件。通过荧光猝灭法测定曲克芦丁片中芦丁的含量。结果表明制备最佳条件为豇豆1.2 g、反应温度170℃、反应时间3 h、溶剂水20 mL。该条件所得碳量子点测得曲克芦丁片中芦丁的标示量为93.23%。以豇豆为碳源合成碳量子点,该方法简单,易于工业化,可用于测定芦丁的含量。A new type of fluorescent carbon quantum dots was prepared with cowpea as carbon source.It was prepared by one-step hydrothermal synthesis.Taking fluorescence intensity as index,the effects of temperature,time,quality and solvent on the preparation were explored through single factor and orthogonal experiments,and the optimal preparation conditions of carbon quantum dots were determined.The content of Rutin in troxerutin tablets was determined by fluorescence quenching method.The results showed that the optimum preparation conditions were as follows:cowpea was 1.2 g,reaction temperature was 170℃,reaction time was 3 h and water was 20 mL.The labeled amount of Rutin in troxerutin tablets was 93.23%.Carbon quantum dots were synthesized by cowpea as carbon source.The method was simple and easy to industrialization,and could be used to determine the content of rutin.
