摘要
本文研究了卡尔曼滤波法在混合稀土同时测定中的应用。实验中采用含阳离子表面活性剂溴化十六烷基三甲基铵的配合体系作为测量体系，有效地克服了显色剂吸收对测定的干扰，提高了分析结果的准确度．用于多组轻、重两元混合稀土的同时测定，所得回收率为９３～１０９％。
In this paper, the method for simultaneous determination of mixed light and heavy rare-earth elements using Kalman-filtering spectrophotometry has been studied. Tit complex system containing canon surface active agent CTAB is used as the measurement system, so the interference of the developer on measurement can be avoided and analytical results can be obtained very accurately. The recoveries of results are 93～109%.
