Abstract

The ubiquity and ecotoxicity of tri (1,3-dichloro-2-propyl) phosphate (TDCPP) in aquatic environments make it essential to develop efficient related treatment techniques. The present research aims to systematically explore the mechanisms and toxicity changes of TDCPP degradation through UV-driven hydrogen peroxide process (UV/HO). The results revealed degradation efficiency of TDCPP attained 95 % with 0.5 mM HO, corresponding to a reaction rate constant () of 0.04919 min. Furthermore, three typical chlorinated OPEs (Cl-OPEs) were simultaneously degraded by the UV/HO process, with different degradation efficiencies, according to the following order: TCEP

紫外线活化过氧化氢降解磷酸三（1,3-二氯-2-丙基）酯（TDCPP）：机理、途径和毒性评估

由于磷酸三（1,3-二氯-2-丙基）酯（TDCPP）在水生环境中无处不在且具有生态毒性，因此开发高效的相关处理技术至关重要。本研究旨在系统探讨紫外线驱动过氧化氢过程（UV/HO）降解 TDCPP 的机理和毒性变化。结果表明，在 0.5 mM HO 的条件下，TDCPP 的降解效率达到 95%，反应速率常数（）为 0.04919 分钟。此外，三种典型的氯化 OPE（Cl-OPE）同时被紫外/HO 过程降解，降解效率不同，顺序如下：TCEP

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
