Kalman滤波同时测定苯酚和2,4-二氯苯酚

Kalman Filter Simultaneous Determination of Phenol and 2,4-Dichlorophenol

提出了苯酚和2,4-二氯苯酚混合体系非线性吸光度表示式,即非线性吸光度由两组分各自对吸光度的贡献、由于混合而导致的两组分各自贡献的改变以及交互作用项三部分构成.依据非线性吸光度,利用非线性Kalman滤波紫外分光光度法同时测量了苯酚和2,4-二氯苯酚混合体系.回收实验表明,非线性吸光度分析法无论是平均回收率还是平均相对误差均优于线性吸光度分析结果,并且在整个实验范围内,非线性吸光度分析法具有非常好的稳定性.

An analysis method of nonlinear absorbance for binary composition mixture of phenol and 2,4-dichlorophenol is proposed.The nonlinear absorbance was composed of the offer from both of themselves and the change by other’s being,as well as the both interactions.Nonlinear Kalman filter UV spectrophotometric was used to determinate the mixture system of phenol and 2,4-dichlorophenol.The recovery experiment shows that the nonlinear absorbance analysis method is not only more exact than linear absorbance analysis ...
