摘　　要：用硝酸-氢氟酸-高氯酸-磷酸体系分解土壤样品,在磷酸(1+4)介质中,直接采用原子荧光光度法测定锗。该方法检出限为2.9×10-9,相对标准偏差RSD为1.02%。经国家一级标准物质验证,测定结果与标准值吻合。The soil and stream sediment samples are decomposed with HNO3-HF-HClO4-H3PO4 system.Germanium in the samples is determined by atomic fluorescence spectrometry in（1＋4） H3PO4 media.The detection limit of the method is 2.9×10-9.The method has been applied in the determination of Germanium in national standard reference materials and the results are in agreement with the certified values with precision of 1.02 %（RSD,n=11）.
