Novel AOPs-Based Dual-Environmental Digestion Method for Determination of Total Dissolved Nitrogen in Water

Abstract: Based on a synergistic digestion method of ultraviolet combined with ozone (UV/O3), this article investigates the reaction characteristics of nitrogen-containing compounds (N-compounds) in water and the influence of ions on digestion efficiency. In this respect, a novel and efficient AOPs-based dual-environmental digestion method for the determination of total dissolved nitrogen (TDN) in waters with complex components is proposed, in the hopes of improving the detection efficiency and accuracy of total nitroge… Show more

“…Therefore, the empirical constant R ct 36 is introduced to simplify the equation defined as Equation ( 20) obtained from engineering experiments representing the rate of the time integral of [•OH] to the time integral of [O 3 ] in the closed reaction system from the beginning to the end of the reaction. Parameter t in Equation (20) represents the reaction time.…”

“…The time integral of [O 3 ] can be obtained by measuring the [O 3 ] in solution at a fixed time interval, and then fitting the curve of [O 3 ] ∼ 𝑡 to obtain the corresponding integral area. Equation ( 22) is obtained by taking Equation (20) into Equation (19). 36 The second-order reaction kinetic equation of p-CBA with •OH is shown in Equations ( 23)- (24).…”
