摘要：
The light emission produced by thiourea in oxidation process by permanganate in acidic solution in the presence of Ru(phen) 2+ 3 is used to determine 1.0×10 -8 \|1.0×10 -5 mol/L thiourea. The limit of detection is 9.8×10 -9 mol/L and the relative standard deviation is 1.1% for a 1.0×10 -5 mol/L thiourea solution ( n =10). The method was applied satisfactorily to the determination of thiourea.
