Determination of Trace Cobalt in Water Samples by Flame Atomic Absorption Spectrometry After Cloud Point Extraction

LI Jing, LIANG Pei~*, SHI Ta-qing(Center for Analysis and Testing, Central China Normal University, Wuhan 430079)  
A method for the determination of trace cobalt in water samples by flame atomic Absorption spectrometry after cloud point extraction was proposed. The effect of experimental conditions such as pH, concentration of chelating agent and surfactant, and equilibration temperature and time on cloud point extraction was discussed. The chemical variables affecting the separation and extraction recovery were optimized. Under the optimum conditions, the detection limit was 3.28 ng·mL~(-1) for cobalt with relative standard deviation of (4.1% (n=10).) The proposed method was applied to the determination of trace cobalt in water samples with satisfactory results.
