A method for the determination of silver,boron,tin,molybdenum and lead in geochemical exploration samples by emission spectrometry is developed. K_2S_2O_7,NaF,Al_2O_3 and carbon powder are used as buffers and Ge as internal standard.

• 以K2S2O7、NaF、A l2O3和炭粉为缓冲剂,Ge为内标,电弧发射光谱法测定勘查地球化学样品中Ag、B、Sn、Mo、Pb。
