This document specifies evaluation methods for determining the content of reactive oxygen species (ROS) used in the FB-facilitated advanced oxidation for pollution abatement in the wastewater treatment process.

u000b

The probe based kinetic model is applicable to systems that generate ROS in substantial quantities, rather than at physiological concentrations, and is applicable to short-lived ROS. However, it is not applicable to long-lived ROS, such as ozone (O3) and hydrogen peroxide (H2O2).

u000b

The probe based kinetic model method specifies:

u000b

cumulative concentration of different types of ROS during the reaction process;

u000b

concentration of different types of ROS at each time point during the reaction process.

u000b

This method does not define the mechanisms of ROS generation, nor the correlation between bubble size and ROS production.
