卡尔曼滤波-分光光度法同时测定邻、间、对硝基甲苯
DIRECT SIMULTANEOUS DETERMINATION OF o,m,p NITRONETHYLBENZENE IN MIXTURE USING SPECTROPHOTOMETRY COMBINED WITH KALMAN FILTER
【摘要】 本文介绍了Kalman滤波法的基本原理及其在分光光度多组分分析时测量模型误差的修正方法。
【Abstract】 The basic principle of Kalman filter and its modified method, including forgetting factor and enhancing dimensions of vector, for the error correction of measurement model in spectrophotometric determination of multicomponents were introduced. Combining forgetting factor with enhancing dimensions of vector,the recursive effect of Kalman filter method was improved. The result of modified Kalman filter was compared with other three chemometric methods,including target transformation factor, iterative target transformation factor and artificial neural network. This method can apply to direct simultaneous determination of o,m,p nitronethylbenzene in mixture without any preliminary chemical separation.
