摘　　要：对光泽精化学发光体系的动力学性质、荧光光谱、化学发光光谱及化学发光机理进行研究和探讨。详细研究了光泽精 - H2 O2 - Co( )流动注射化学发光体系的最佳分析条件。结果表明 ,当光泽精 (L c)为 2 .5×10 - 5mol/L、H2 O2 为 0 .5 mol/L、Na OH为 0 .4 mol/L、CTMAB为 2 .0× 10 - 5mol/L时 ,测定 Co( )的校准曲线线性范围为 0 .0 5— 2 0 0μg/m L ,检出限为 0 .0 1μg/m L。对 10μg/m L Co( )连续测定 7次 ,相对标准偏差为 1.7%。A thorough study of the lucigenin H 2O 2 NaOH chemiluminescence system is reported.A possible mechanism for this lucigenin chemiluminescence reaction is proposed on the basis of studying chemiluminescent spectra and fluorescent spectra.A new method has been recommended for the determination of trace amounts Co(Ⅱ) by chemiluminescence with flow injection analysis.The proposed method gives a limit of detection of 0.01μg/mL and Beers law is obeyed in the concentration range from 0.05μg/mL to 200μg/mL.The relative standard deviation is less than 1.7%.
