Table 3: Acetamiprid degradation rates using P3 and P4 as photosensitizers in IWWTP samples. for effluent sample 1, utilizing the two polymeric photosensizers P3 and P4, under both pH conditions. The results demonstrate that the supported photosensizers can be effectively used for the degradation of Acetamiprid in effluent wastewater at its natural pH and more efficiently at pH = 10. In all cases, the degradation kinetics ranged from 300 to 360 min under such conditions. It is important to note that the proposed solution in this study addresses the limitations of traditional Fenton and photo-Fenton methods regarding their applicability at the effluent's natural pH. This also can minimize the risk associated with pH adjustments, where ions that can interfere with the reaction mechanism and affect the degradation rate of Acetamiprid [69; 70]. Table 4 compares examples of different methods for the degradation of Acetamiprid, with the operational pH media and the kinetic times required to achieve complete degradation of the insecticide. The table provides examples of Fenton methods from key studies in the literature. In general, Fenton and photo-Fenton methods achieve Acetamiprid degradation rates exceeding 99% within approximately 1 h. These methods usually operate in a homogeneous medium and have been successfully applied on multiple occasions to wastewater treatment [43; 46; 67]. As discussed in the introduction section, the current state-of-the-art literature describes significant innovations in order to enhance efficiency of Fenton processes, particularly in terms of kinetics, achieving degradation within a few minutes. Additionally, some innovations have focused on expanding the pH operational range of the Fenton, such as the work by [PERSON], which improved materials using monodentate ligands to extend the pH range of action [45], or [PERSON], who utilized graphene-oxide-based metal ferrites as Fenton-like as heterogeneous photocatalysts, successfully increasing the operational pH range [71]. The results obtained in this study should be compared with the examples described which apply the Fenton method at the natural pH of wastewater effluents, even with a higher degradation %. As outlined in the objectives, this work successfully describes an alternative to the Fenton and photo-Fenton methods for the removal of Acetamiprid at both the effluent pH and basic pH levels. Although this study demonstrates slower kinetics than the acidic pH Fenton method, the kinetics at a mildly basic pH are comparable in terms of time.
