全因子设计优化UV/H2O2工艺对合成废水中甲苯二胺的降解

甲苯二胺（TDA）是一种主要的致癌芳香污染物，在一些工业过程中，它通常被用作甲苯二异氰酸酯（TDI）和染料的中间体。高级氧化工艺（AOPs）是降解和矿化工业废水中各种有机难降解污染物的非常有效和可靠的解决方案之一。几乎没有任何研究工作来探索利用UV/H2O2工艺降解TDA的反应机理。因此，在这项新的实验工作中，考察了UV/H2O2工艺作为一种有效的AOP对合成废水中TDA的降解。采用全因子设计（FFD）研究了TDA初始用量、pH和H2O2初始用量等操作参数对TDA去除性能的影响。统计优化证明了一个非常令人满意的决定系数（R2=0.9445，R2adj=0.9150，R2pred=85.33）。全面讨论了影响TDA降解的各个主要参数的根本原因和机制。不同pH条件下H2O2的分解直接决定了UV/H2O2降解TDA过程的机理。实验设计预期的最佳情况如下：TDA初始剂量为37.0365mg/L，pH为7.04919，H2O2初始剂量为44.1792mM。在最佳点，预期和实际TDA降解率分别为104.661%和98.5%。实验结果表明，UV/H2O2-AOP能成功降解废水中的TDA。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
