摘要
提出了用交流示波极谱法测定电镀液中的微量铅,并研究了各项试验条件.铅在0.100~10.0 mg/mL范围内,标准偏差在0.200%~0.220%之间,相对标准偏差为4.29‰~4.73‰.该法可用于硫酸盐镀锌技术的电镀液中微量铅的分析测定,其加标回收率在98.0%~103%之间,操作简便,测定快速,分析可靠.
The application of A C oscillopolarographic method in The determination of micro amount of lead in electrolyte was studied. The lead content in the electrolyte is 0. 100~10.0 mg/mL and the standard deviation is within 0.20%-0.22% and the relative standard deviation is within 4.29‰~4.73‰ .The method can be used in the determination of micro amount of lead in vitriol galvanizing electrolyte. The recovery rate is 98.0%-103%. The method is easy to operate and quick in determination with reliable analysis results.
