Comparative study between flame atomic absorption spectrometry and graphite furnace atomic absorption spectrometry and inductively coupled plasma optical emission spectrom-etry for the determination of copper in surface water
The copper in surface water was measured by flame atomic absorption spectrometry(FAAS)and graph-ite 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;com-pared with FAAS and ICP-OES method,GF-AAS method had the advantages of lower detection limit,higher sensitiv-ity and accuracy for the determination of low concentration environmental samples.
