| Abstract: | ICP-OES method for direct injecting determination of copper content in seawater was studied by selecting spectral lines and adjusting the best instrument parameters. Results shows that： in the 0-50μ/L linear range, correlation coefficient can reach 0.999 6, the detection limit is 0.5 μ/L, the addition standard recovery is 102%-105%, RSD ≤4.7. Direct injection-ICP-OES method for the determination of trace copper in seawater has the advantages of simple pretreatment, high sensitivity, low detection limit, less interference, wide linear range, simple operation, fast. |
