| Abstract: | The technique combining the flow injection system of on-line ion-exchange preconcentration and flame atomic absorption spectrum is proposed for the determination of trace nickel in water.A manifold of the on-line ion-exchange preconcontration in which two columns are used in turn for normal concentration and reverse elution has been designed.The system is simple but reasonable.The proposed method is rapid and efficient.This method can increase the sensitivity of nickel by 12 times and make the sampling rate achieve at 30 samples per hour. |
