At very ,acidic, condition (pH 2–3), the acidification of the solution using HCl generates much HClO·-from the reaction between Cl-and ·OH. As a result, the degradation efficiency is decreased due to the lower reactivity of HClO· - compared to ·OH (Nezamzadeh-Ejhieh and Khorsandi 2010a,b, Pourtaheri and Nezamzadeh-Ejhieh 2015).
