| 摘 要： | 本文采用卡尔曼滤波(KF)递推法,以苯基荧光酮-溴化十六烷基吡啶与钛,钼的显色体系同时测定钛和钼,同时以柠檬酸和抗坏血酸掩蔽干扰,并引入误差校正因子来校正加掩蔽剂后在所测波段范围内所造成的残余背景吸收,用于实际钢样分析,获得较满意的结果。

| Abstract: | A spectrophotometric method based on Kalman filter is described for simultaneous determination of titanium and molybdenum with Ti (Mo)-2. 6. 7-trihydroxy-9-phenylfluorone and cetylpyridinium bromide system. In this study,Kalman filtering is used as a "chemometrics filter".which ,in combination with chemical masking reagents,suppresses the interference from other ions, the method is accurate and selective. The method can be directly applied to the spectrophotometric determination of Ti and Mo in steel with satisfactory results. |
