摘要
通过实验验证了在酸性介质存在条件下用ICP-MS法测定地电化学(泡塑)样品中痕量金的可行性,在稀释因子存在条件下得到了方法的检出限为3 ng、精密度为1.40%。同时,通过制备模拟负载不同金含量的泡塑样品,计算加入标准物质回收率为88.80%～107.37%;与GAAS法测定结果进行显著性检验发现两组数据之间无显著性差异,其测定结果同样真实、可靠。
It was verified as feasible to determine trace gold in geoelectrical chemical samples（foam） by ICP-MS method in acidic medium.In the existence of dilution gene,the determination limit of the method was 3 ng and the precision of the method was 1.40 %.The foam samples containing different content of gold were obtained through simulating experiments and the recoveries of standard materials were between 88.80 %-107.37 %.There were no obvious differences with the contrast results by GAAS method.They were also true and reliable.
