摘　　要：含钡铅矿中铅测定过程中,前处理采用酸溶形成硫酸铅沉淀时,易形成硫酸钡铅的复盐沉淀,使铅的分析结果偏低。对现有铅矿的分析方法进行优化,有效消除了钡对铅测定的影响,可实现含钡铅矿中铅的准确测定。For lead determination in barium-containing galena, lead ＆ barium sulfate could be easily formed in the course of lead sulfate precipitation pretreated by acid dissolution, which could result in lower detection value for lead. The current lead determination method is optimized, which effectively eliminates barium＇s impact on lead de- termination and realizes to obtain accurate lead determination in barium-containing galena.
