| 摘 要： | 在波长范围200～400nm测定苯酚、苯胺和苯甲酸混合液的吸收光谱，用离散小波变换（DWT）对光谱数据进行处理，再用支持向量回归SVR方法进行建模，建立了离散小波变换一支持向量回归方法（DWT—SVR）。方法用于模拟样品和污染水样中苯酚、苯胺和苯甲酸的同时测定，结果满意。

| Abstract: | A approach was proposed for the determination of phenol,aniline and benzoic acid by discrete wavelet transform(DWT) and support vector regression(SVR).In the approach,the absorption spectra in the range of 200~400 nm for phenol,aniline and benzoic acid mixed system was determined firstly,DWT was then employed for the obtained data preprocessing,finally SVR methods being used for calibration model.With application of the method in determination of phenol,aniline and benzoic acid compounds in the simulated sa... |
