本文首次将罗丹明S应用于镉的荧光熄灭法测定,由于PVA-124的稳定作用,克服了罗丹明类试剂常须经萃取测定操作繁杂之不足。在加入各种试剂后,直接进行水相荧光测定。方法简便、灵敏,精密度好。
In this paper, rhodamine S was first applied to the determination of cadmium by fluorescence quenching method. Due to the stabilizing effect of PVA-124, rhodamine-based reagents were often overcome by extractive determination. After adding various reagents, direct determination of aqueous fluorescence. Method is simple, sensitive, good precision.
