| Abstract: | In this paper, a new method for the determination of copper in surface water by on-line pre-concentration based on copper() absorbed on a diatomite column was reported. Optimization of experimental parameters was discussed. The concentration efficiency is 27.6. The relative standard deviation is 3.52% (20 gL~(-1), n=11). The proposed method has been applied to the determination of surface water. Recoveries of copper() in water samples are 97.0%105.0%. |
