系数倍率和卡尔曼滤波紫外分光光度法同时测定发洗剂中的苯酚、间苯二酚和水杨酸

SIMULTANEOUS DETERMINATION OF PHENOL, RESORCINOL AND SALICYLIC ACID IN THE SHAMPOO BY K-FACTOR AND KALMAN FILTERING UV SPECTROPHOTOMETRY

用系数倍率和卡尔曼滤波紫外分光光度法同时测定发洗剂中苯酚、间苯二酚、水杨酸的含量,苯酚、间苯二酚、水杨酸的线性回归方程分别为:A=0.00546+0.01762X,r=0.9999;A=0.00245+0.01606X,r=0.9999;A==0.00748+0.02491X,r=0.9999。回收率分别为97.8％～102.3％、99.9％～102.3％、99.3％～103.2％。

The contents of phenol, resorcinol and salicylic acid in shampoo were simultaneously determined by K-factor and Kalman filtering UV spectrophotometry. Linear equation of phenol, resorcinol and salicylic acid are A =0. 00546 +0. 01762X, r = 0. 9999; A =0. 00245 +0. 01606X,r =0. 9999; A = -0. 00748 +0. 02491X, r =0. 9999 respectively. And the recoveries are 97. 8% ~ 102. 3% , 99.9% ~ 102. 3% and 99. 3% ~ 103. 2% respectively.
