摘　　要：使用荧光法测定不同塑料荧光增白剂的最大激发波长和最大发射波长,建立塑料荧光增白剂定性分析方法;通过荧光法实验获得荧光法测定塑料荧光增白剂OB溶液含量的条件:激发波长369 nm,发射波长435 nm,线性范围0.12～6.0 mg/L,建立了塑料荧光增白剂OB定量分析方法。结果显示荧光法是一种测定塑料荧光增白剂定性定量的简单而有效的方法。The maximum excitation wavelength and emission wavelength of fluorescent whitening agents in plastics were measured and qualitative method was built with fluorescent method. In the test, optional conditions for quantitative determination of fluorescent whitening agent OB were as following： The excitation wavelength was 369 nm, emission wavelength was 435 nm. The fluorescence positively linear correlated with concentration of OB when the concentration was 0. 12 was simple and efficient method to qualitative and plastics. 6.0 mg/L. These results showed that fluorescent method quantitative determination of fluorescent whitening agents in
