摘要
本法采用硝酸分解试样,在醋酸和醋酸钠缓冲溶液中,用硫酸亚铁铵容量法,对铅黄铜中铅量的测定条件进行了试验研究。方法的准确度和精密度可靠,方法的回收率为98%～101%。
With this method,nitric acid is used to resolve the sample,in buffer solution of acetic acid and sodium acetate,ammonium ferrous sulfate volumetric method is adopted to research the determining conditions of lead content in lead brass.The accuracy and precision of the method is reliable and the recovery rate is between 98%～100%.
