摘　　要：采用吸光系数法对二氯二茂钛原料药进行含量测定。 391nm处测得E1%1cm =98 32 ,平均回收率为 98 77%～10 1 74% ,相对标准差RSD =0 .12 %～ 0 .6 6 %。测定不同温度 ,湿度下放置不同时间原料药的含量 ,与工作曲线法相比 ,两者之间无显著性差异。WT5”BZ] To establish specific absorptivity method for determining the concentration of Cp 2TiCl 2.The UV detector wavelength was 391 nm and its absorptivity was 98.32%.The average recovery was 98.77%～101.74%. The RSD was about 0 12%～0 66%.The content was determined at various temperature and humidity conditions.The results indicate that there is no significant difference between specific absorptivity method and linear regresson method.[WT5”HZ]
