摘　　要：将自适应卡尔曼滤波(AKF)用于ICP-AES信号处理,并对影响滤波的因素进行了探讨,对于一些典型光谱干扰,测定的回收率为85～105％。在选择了合适的初始参数条件下,AKF法分析结果优于常规卡尔曼滤波(NKF)法。Adaptive Kalman filtering has been applied to the analysis of inductively coupled plasma-atomic emission spectrometry. Some influent factors on filtering have also been investigated. The recoveries were within 85%-105% and better than those of the normal Kalman filtering obviously under the selected fitting initial parameters.
