摘　　要：本文合成了铽-2,6-吡啶二羧酸二元稀土配合物,采用循环伏安法(CV),以过硫酸钾为共反应剂,探讨了其电化学发光性能.根据盐酸左氧氟沙星对该体系电化学发光的增敏作用,建立了一种测定盐酸左氧氟沙星的新方法,其线性范围为1.0×10-4 mol/L-1.0×10-6 mol/L,检出限为3.3×10-7 mol/L,线性方程为Y=561.3+66.7X,并对模拟试样进行了检测,结果较为满意.We synthesize the terbium complex of Tb（DPA）3（NO3）3（H2O）3,and study the ECL behavior with cyclic voltammetry.Under the optimized conditions,we find that the levofloxacin hydrochloride could highly strengthen the ECL intensity of Tb（DPA）3（NO3）3（H2O）3.Based on this,we establish a new method for the determination of levofloxacin hydrochloride.The enhanced ECL intensity versus the concentration of Levofloxacin hydrochloride is in a good linear relationship over a concentration range from1×10^-4 mol/L to 1.0×10^-6 mol/L,linear regression equation is Y=561.3＋66.7X,correlation coefficient R=0.9974,the detection limit is 3.3×10^-7 mol/L.And the simulation samples are tested and the results are satisfactory.
