“…Previous studies also have found that increasing OH radical production is done due to certain concentrations of H 2 O 2 , and if H 2 O 2 is added to the process it causes limitation and removal of the procedure [50][51][52][53]. 43.4, 59.85, and 63.88%, respectively, which is consistent with our previous study [53][54][55].…”

The aim of our study was to investigate the effectiveness of Fenton and photo-Fenton processes for removing anionic surfactants from aqueous solutions. The study was conducted using 200 mgL and 120 mgL -1 ferrous ion) were 69.38 and 86.66%, respectively, which is consistent with the significant increase in the rate of LAS removal efficiency with reaction time (P<0.05). In conclusion, anionic surfactants removal was significantly correlated with reaction time by both methods, but showed less dependence on H 2 O 2 and Fe 2+ concentrations.

“…On the other hand, a high dose of Fe 2+ is not practically advised, but a low dosage is advised in industrial applications since its highly used dosage demands higher costs and later treatment may be needed. It also causes more sludge which, in turn, increases removal costs [51,55].…”

In this study, solar photo-Fenton reaction using compound parabolic collectors reactor was assessed for removal of phenol from aqueous solution. The effect of irradiation time, initial concentration, initial pH, and dosage of Fenton reagent were investigated. H 2 O 2 and aromatic intermediates (catechol, benzoquinone, and hydroquinone) were quantified during the reaction to study the pathways of the oxidation process. Complete degradation of phenol was achieved after 45 min of irradiation when the initial concentration was 100 mg/L. However, increasing the initial concentration up to 500 mg/L inhibited the degradation efficiency. The dosage of H 2 O 2 and Fe ?2 significantly affected the degradation efficiency of phenol. The observed optimum pH for the reaction was 3.1. Phenol degradation at different concentration was fitted to the pseudo-first order kinetic according to Langmuir-Hinshelwood model. Costs estimation for a large scale reactor based was performed. The total costs of the best economic condition with maximum degradation of phenol are 2.54 €/ m 3 .

“…Some of them are coagulationflocculation [23], anaerobic biodegradation [24] [25], photodegradation [26], ozonization [27], ion exchange [28], advanced oxidation processes [29] [30], nanofiltration [31] [32] and adsorption on different activated carbons [28] [33]- [35]. However, most of them require substantial financial input and their use is often restricted because of cost factors overriding the importance of pollution control.…”

The presence of pesticides in the environment is of great concern due to their persistent nature and chronic adverse effect on human health and the environment. Water bodies are subject to pollution by organochlorine pesticides, especially in developing countries, where water pollution is a key sustainability challenge. Hence, activated carbon is considered a universal adsorbent for the removal of organochlorine pollutants from water. Activated carbon from Acatia etbaica was prepared using traditional kilns with low investment costs. Pesticides such as aldrin, dieldrin and DDT were selected for adsorption because of their common usage in agricultural and malaria control activities and may occur in high concentrations in surface waters that are used as drinking water sources. The effect of the adsorbent dose and initial concentration were investigated. To describe the equilibrium isotherms the experimental data were analyzed by the Langmuir and Freundlich isotherm models. The Freundlich model gave the best correlation with the experimental data. Activated carbon prepared from Acacia etbaica was found to be an effective and low-cost alternative for the removal of organochlorine pesticides from aqueous solutions. The preparation method allows the use of this material by local communities for effective remediation of pollution * Corresponding author. A. Gebrekidan et al. 279by pesticides.
