研究了胭脂红（C.I.）采用响应面法优化了H2 O2存在下紫外光催化降解天然红4的工艺条件。根据方差分析（ANOVA）的结果，该模型可以用来导航的设计空间。结果表明，胭脂红的降解反应对胭脂红浓度、H2 O2浓度、pH和反应时间等独立因素非常敏感。D-最优设计模型与实验数据拟合良好，R-2和R-adj（2）相关系数分别为0.998和0.997。(C)2008 Elsevier B. V.保留所有权利。
In this study, the photolytic decoloration of carmine (C.I. Natural Red 4) via UV radiation in the presence of H2O2 was optimized using response surface methodology (RSM). According to analysis of variance (ANOVA) results, the proposed model can be used to navigate the design space. It was found that the response of carmine degradation is very sensitive to the independent factors of carmine concentration, H2O2 concentration, pH and reaction time. The proposed model for D-optimal design fitted very well with the experimental data with R-2 and R-adj(2) correlation coefficients of 0.998 and 0.997, respectively. (C) 2008 Elsevier B.V.
