Scope

This International Standard specifies evaluation methods for content of the ROS used in the FB-facilitated advanced oxidation for pollution abatement in the treatment process.

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

Using this method provides the following information:

(i) cumulative concentration of different types of ROS during the reaction process.

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

However, this method does not divulge the mechanisms of ROS generation, nor the correlation between bubble size and ROS production.
