实验发现:铜离子Cu2+明显增强了Luminol-NaOH和Luminol-Ca(OH)2两种水溶液的声致荧光强度,并使它们的最大声致荧光峰分别发生了6nm和9nm的红移现象.但这种离子对Luminol-Na2CO3水溶液的影响与上述相反,并对应发生了5nm的篮移现象.然而,Cu2+对这3种溶液的声致荧光的发射波长均不构成严重影响.
It was found that the copper (II) -containing Cu2 + enhanced the acoustically-induced fluorescence intensity of both Luminol-NaOH and Luminol-Ca (OH) 2 aqueous solutions and caused their redox shifts of 6nm and 9nm respectively. However, the effect of this ion on the Luminol-Na2CO3 aqueous solution is opposite to that described above, and a corresponding shift of 5 nm occurs. However, Cu2 + did not have a serious impact on the acoustic emission wavelengths of the three solutions.
