Advanced oxidation technology like Fenton and EF-Fenton are used to remove organophosphate esters (OPEs), including TCEP and TEP, in water in this study. A series of system experiments and the establishing of dynamical equations are for the purpose of finding out the characteristic of degradation of OPEs. The main conclusions are as follows: (1) Under certain conditions, it is obviously that the initial concentration of OPEs, H2O2 and Fe2+ all have a positive correlativity with the reaction rate of Fenton degrades OPEs in water; (2) The reaction rate of TEP in water by EF-Fenton process is influenced by initial electric potential and the concentration of Fe2+, TEP. The electric potential has a greater influence; (3) Compared to ordinary Fenton advanced oxidation technology, EF-Fenton has merits like reacting more completely and low energy consumption, but the reaction time is longer; (4) The dynamical equations of TCEP, TEP in water by Fenton process and the TEP in water by EF-Fenton process are: , , .
