交流电弧发射光谱法测定地球化学样品中的高含量锡
|
摘要
建立了交流电弧发射光谱法测定化学样品中锡的方法。以氧化锌、氟化钠、硫粉为缓冲剂,改善元素蒸发行为;以锗为内标,样品与缓冲剂比例为1∶1。根据不同含量的锡选择不同级别灵敏线进行分析,采取内标法,建立浓度与相对强度之间的线性关系,计算出样品中锡的含量。实验中可以将锡的分析上限提高到x%,同时避免由稀释样品带来的分析误差。方法相对标准偏差(RSD,n=12)小于7%,测定了国家一级地球化学标准物质,结果与标准值相符。
In this paper a method for determination of tin in chemical samples by alternating current arc emission spectrometry was described.Zinc oxide,sodium fluoride and sulfur were used as buffer to improve the evaporation behavior of elements,and germanium was used as internal standard.The ratio of sample to buffer was 1∶1.According to different content of tin,different levels of sensitive lines were selected for analysis.The internal standard method was adopted to establish the linear relationship between the concentration and relative strength,and to calculate the content of tin in the sample.This method can increase the upper limit of tin analysis to x%,and avoid the analysis error caused by diluted sample.The relative standard deviations(RSD,n=12)was all less than 7%,The method was validated by the determination of the national geochemical standard reference materials,and the result was in agreement with the standard value.
