摘要
采用火焰原子吸收光谱法(FAAS)、石墨炉原子吸收光谱法(GF-AAS)和电感耦合等离子体发射光谱法(ICP-OES)分别测定地表水中的铜,对检出限、精密度、正确度、低浓度环境样品测试等指标进行对比。实验结果表明,三种方法对于测定地表水中铜,测试结果无显著差异;与FAAS和ICP-OES法相比,GF-AAS法具有较低的检出限、较高灵敏度,对于测定低浓度环境样品具有较高的准确性。
The copper in surface water was measured by flame atomic absorption spectrometry(FAAS)and graphite furnace atomic absorption spectrometry(GF-AAS)and inductively coupled plasma optical emission spectrometry(ICP-OES),and the detection limit,precision,accuracy and low concentration environmental samples were compared.The experimental results showed the three methods had no obvious difference between measurement results;compared with FAAS and ICP-OES method,GF-AAS method had the advantages of lower detection limit,higher sensitivity and accuracy for the determination of low concentration environmental samples.
