摘要
将卡尔曼滤波与分光光度法结合,用于同时测定安钠加注射液中苯甲酸钠和咖啡因的含量,其平均回收率分别为99.90±0.32%,100.10±0.28%。本法也适用于其它多组分体系分析。
Caffeine and Sodium benzoate in Coffeinum natrio benzocium injection were determinee sim-ultaneously by Kalman filter-spectrophotometry without any separation. The average recoverieswere 100.1±0.28% and 99.9±0.32 % respectively.
