摘　　要：在波长200—400nm范围内,研究苯酚、苯胺和苯甲酸的光谱行为。采用离散小波变换(DWT)对光谱数据进行处理,独立成分回归(ICR)方法建模,建立了离散小波变换-独立成分回归(DWT-ICR)稳健模型。方法用于模拟样品中苯酚、苯胺和苯甲酸的测定,结果满意。A approach for the determination of phenol,aniline and benzoic acid by discrete wavelet transform（DWT） and independent component regression （ICR） was proposed.The absorption spectra in the range of 200—400nm for phenol,aniline and benzoic acid mixed system was determined firstly,discrete wavelet transform（DWT） was then employed for the obtained data preprocessing,finally independent component regression（ICR） methods being used for calibration model.With application of the method in determination of phenol,aniline and benzoic acid compounds in the simulated samples and polluted water samples,the DWT-ICR is a better method than ICR.The result is satisfied.
