摘　　要：本法以氧化铝、焦硫酸钾、氟化钠、石墨粉的混合物为缓冲剂,锗为内标元素,一次取样,用垂直电极发射光谱法,同时测定铜、铅、锌元素。方法检出限,精密度及准确度均能满足化探样品的要求。并提供了一个简便、快速、成本低的光谱分析方法。This method adopts the mixture of aluminium oxide, potassium pyrosulfuric acid, sodium fluoride and graphite powder as buffer, germanium as intemal standard element, one-time sampling, vertical electrode emission spectrometry and simultaneously measurement of copper, lead and zinc. The detection limit, precision and accuracy can a convenient, quick and economic spectrum analysis method. all meet the requirements of geochemical exploration samples. This is
