摘要
本文建立了湿法溶解样品,经聚氨酯泡塑分离富集后,利用交流塞曼扣背景技术,用石墨炉原子吸收光谱法测定地球化学样品中的Tl。该法对样品的吸附体系进行了系统的研究,同时研究了适合交流塞曼效应-石墨炉原子吸收光谱仪测定Tl的最佳条件。经过试验,得出该方法检出限为：0.001μg.g^-1,精密度为：5.49%-8.35%,且准确度较高,经过国家一级地球化学标准物质验证,该方法准确、可靠。
A new determination method was established.The thallium in geochemical samples was separated and concentrated with polyurethane by inverse effect-graphite oven AAS.The absorption system of sample was studied,meanwhile the best determination conditions of inverse effect-graphite oven AAS were studied.The results showed that the limited was 0.001μg·g-1,the precision was 5.49%~8.35%.The accuracy is high.The method was accurate and reliable.
