提出了邻氯苯酚与2，4–二氯苯酚混合体系非线性吸光度表示式．非线性吸光度由2组分各自对吸光度的贡献和由于混合而导致的2组分各自贡献的改变以及交互作用项3部分构成．依据该式，利用非线性 Kalman 滤波法处理了42组邻氯苯酚与2，4–二氯苯酚的标准混合溶液在260～300,nm区间的紫外光谱数据，在混酚的标准溶液中酚的质量浓度均在0.1～15,mg/L 范围内．利用偏最小二乘法，将其制作成扩展 Kalman 滤波标准工作系数矩阵．通过对非线性吸光度关系式Taylor级数展开进行线性化处理，得到其向量函数的Jacobi矩阵，从而完成了非线性Kalman滤波器的设置．回收实验显示，扩展Kalman滤波同时测量邻氯苯酚与2，4–二氯苯酚双组分体系是准确、稳定的．

An analysis method of nonlinear absorbance for binary composition mixture has been 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 interac-tions. Using nonlinear Kalman filter UV spectrophotometric simultaneous determinate mixture of 2,4-dichlorophenol and 2-chlorophenol. Calibration set with 42,standard solutions(range 0.1-15,mg/L)and wavelengths 260-300,nm. Standard work matrix of extended Kalman filter was performed from partial least-squares method. The vectors function Jacobi matrix were obtained by linearized from Taylor series for nonlinear absorbance formula. The recovery experiment showed the extended Kalman filter simultaneous determination of mixture for 2,4-dichlorophenol and 2-chlorophenol that is not only exact,but also stable.
