实验表明 ,Cu2 + 增强了 luminol-Na OH水溶液和 luminol-Ca( OH) 2 水溶液的声致荧光强度 ,并使这两种水溶液的最大声致荧光峰分别发生了 6nm和 9nm的红移 ;Cu2 + 减弱了 luminol-Na2 CO3 水溶液的声致荧光强度 ,并使其最大声致荧光峰发生了 5nm的蓝移 ;但是 ,Cu2 + 并未对上述三种溶液的声致荧光的发射波长范围 3 70～ 750 nm产生明显影响。上述结果至少可以证明 ,这三种 luminol-碱性水溶液或许能成为一类声致荧光发光体系而用于检测 Cu2 + ,甚至其他离子。
The results showed that Cu2 + enhanced the fluorescence intensity of luminol-NaOH aqueous solution and luminol-Ca (OH) 2 aqueous solution, and caused the redox shifts of 6nm and 9nm respectively for the maximum acoustic fluorescence peaks of the two aqueous solutions. Cu2 + Weakened the acoustical fluorescence intensity of luminol-Na2 CO3 aqueous solution and caused a blue shift of 5 nm at the maximum acousto-fluorescence peak. However, Cu2 + did not emit the acoustically-induced fluorescence of the above three solutions at a wavelength of 3 70 ~ 750 nm have a significant impact. The above results can at least prove that these three luminol-alkaline aqueous solutions may be able to be used as a type of sonicating fluorescent system for the detection of Cu2 + and even other ions.
