Based on the aggregation-induced luminescence of glutathione-protected non-noble metal copper nanoparticles (GSH-CuNPs), a fluorescence method for the rapid detection of bismuth (Bi) was developed. The fluorescence intensity of GSH-CuNP solution is good, and the fluorescence can be quenched in the presence of Bi. Based on this principle, a fluorescence mean for the admeasurement of Biwas built. The linear range was 0-100 mmol/L, and the detection limit was 10 mmol/L. The method is simple, rapid, and selective and can be used for the qualitative detection of Bi.
基于谷胱甘肽保护的非贵金属铜纳米颗粒（GSH-CuNPs）的聚集诱导发光，开发了一种快速检测铋（Bi）的荧光方法。GSH-CuNP溶液的荧光强度良好，并且在Bi存在下荧光会猝灭。基于此原理，建立了一种用于测定Bi的荧光方法。线性范围为0-100 mmol/L，检测限为10 mmol/L。该方法简单、快速且具有选择性，可用于Bi的定性检测。
