本文提出了用苯萃取TlCl_4~--亮绿,然后用丁基若丹明B染料配体交换荧光光度法测定铊的新方法。检测限为0.01μg/6.0ml铊。
In this paper, a new method for the determination of thallium by benzene extraction with TlCl_4 ~ - Brilliant Green and then by rhodamine B dye ligand exchange spectrofluorimetry was proposed. The detection limit is 0.01μg / 6.0ml thallium.
