摘要
建立了无水偏硼酸锂熔融-ICP-AES测定岩屑样品中10种造岩元素(SiO_2、Al_2O_3、CaO、TFe_2O_3、K_2O、MgO、MnO、Na_2O、P_2O_5、TiO_2)的分析方法。对4个国家一级岩石标准物质GBW07103、GBW07104、GBW07105、GBW07107进行测定,测定结果与标准值相符,样品精密度(n=6)在0.89%~4.97%之间,加标回收率在90.51%~108.65%之间,方法的检出限为0.28~259.9μg·g^(-1),测定结果满足分析测试要求,为岩屑中造岩元素的分析检测提供了快速、准确的方法。
An analytical method for the determination of ten kinds of rock forming elements(SiO2,Al2O3,CaO, TFe2O3,K2O,MgO,MnO,Na2O,P2O5 and TiO2) in cuttings samples was established by melting-ICP-AES with anhydrous lithium metaborate. Four national rock standards GBW07103, GBW07104, GBW07105 and GBW07107 were determined by the method, and the results were in agreement with the standard values. The sample precision(n=6) was between 0.89%~4.97%, the rate of recovery was 90.51%~108.65% and the detection limit was 0.28~259.9 μg·g^(-1). The result met the determine requirements. The method is rapid and accurate for the detection and analysis of rock forming elements in cuttings samples.
