摘要
研究了以K_2SO_4、S粉、C粉、聚三氟氯乙烯粉、Al_2O_3、MgO混合物作为固体缓冲剂,以Cd为内标,电弧发射光谱法测定多目标地球化学土壤样品中的钼。方法的检出限为0.02μg/g(3S),方法的精密度(RSD)为6.59～11.36%。测定了国家一级地球化学标准物质,结果与标准值相符合。本方法已用于10000多件样品的分析,取得满意的结果。
A method for the determination of silver in multi--Purposes eco--geochemistry soil sample by Level Electrode Emission Spectrometry is invcstigated. K2SO4 ,S powder, carbon powder,polytrifluorochiorocthylene powder, Al2O3 ,MgO are used as solid buffers and Sb as interal standard. The determination limits of the method are 0. 02μg/ g（3S）. The precision of the method arc 6.59 - 11.36% （RSD. n= 49）. The accuracy of the method has been verified by determination of Mo in national geochemical standard samples and the results are in agreement with certified values. More than 10,000 multi--purposes eco--geochemistry soil samples have been analyzed by this method with satistaetory results.
