The presence of copper in aqueous environments such as drinking water has led to several environmental effects, such as flavor and odor. The increase in Cu levels in ground and surface water has been mainly attributed to anthropogenic and natural sources. Consequently, this applied-analytical study aimed to investigate copper removal from urban drinking water through batch reactor electrocoagulation/flotation (ECF) with aluminum electrodes. The copper removal efficiency was evaluated under various operating conditions of current density (0.8–2.4 mA/cm2), initial concentration (1–100 mg/L), pH (3.5–10.5), and time (10–30 min). Cu was determined using the method outlined in the standard procedures (3500-Cu B at 4571 nm). The results indicated that increasing the current density from 0.8 to 2.4 mA/cm2 and the reaction time from 10 to 30 min improved Cu+2 removal efficiency (from 95 to 100%). In addition, the results demonstrated that Cu+2 reduction is 100% with an initial concentration of 100 mg/L, a pH of 7.5, a reaction time of 30 min, and an anode current density of 2.4 mA/cm2. The Taguchi method results for copper removal efficiency show that reaction time is the most significant variable. Furthermore, Cu removal kinetics models in an ECF reactor are second-order (R2 > 0.92). The Cu removal in the ECF reactor is due to redox and adsorption. Moreover, the operational costs of Cu treatment with Al electrode pairs are estimated to range from 8857 and 9636 Rial/kg of Cu removed. Thus, it can be concluded that the ECF process is very efficient in removing Cu from aqueous environments under optimum conditions.

“…In general, the removal of pollutants and pesticides from water sources is accomplished through three main approaches, which include physical, chemical, and biological methods [ [15] , [16] , [17] , [18] ]. The use of adsorption methods [ 19 ], nanofiltration and reverse osmosis [ 20 , 21 ], electrochemical [ 22 ], advanced oxidation processes [ 23 ] and a combination of the above methods have been used to remove diazinon from water sources [ 24 ]. In recent times, the application of advanced oxidation processes (AOPs) has garnered substantial attention as efficient techniques for the eradication of pesticides from water sources [ 25 ].…”

“…[23] Free hydroxyl radicals in the AOPs (advanced oxidation processes) may be created using various techniques such as ultrasonic and UV radiation, [24,25] photodegradation, [11,26,27] and Fenton treatment. [28][29][30] Lately, ultrasonic irradiation has been receiving much attention as an efficient method for the removal of dangerous organic materials in water, particularly CPS. [31][32][33] Nevertheless, the ultrasonication removal rate is in a low degree compared to the photocatalytic and sonophotocatalytic processes.…”

A new nanohybrid photocatalyst named cerium (IV) oxide (CeO 2 )/TiO 2 (titania)/silicon dioxide (SiO 2 ) was firstly synthesized employing the coprecipitation technique to elaborate the degradation efficiency of chlorpyrifos (CPS) as a relatively indelible organophosphorus pesticide in deionized water in photocatalytic and sonophotocatalytic processes. The influence of various parameters, including photocatalyst dosage, the CPS pesticide concentration, pH, and irradiation time, was investigated, and the optimal parameters for photodegradation and sonophotodegradation were determined. The activity and the electrical energy of this photocatalyst in the photodegradation and sonophotodegradation processes were compared, and it was revealed that the sonophotocatalytic process was superior to the photocatalytic one (about 15%).Results depicted that it can be employed four times for the photocatalytic reactions with the same yield of CPS degradation. Besides, the CPS degradation efficiency at the optimum conditions was found to be 81.1% and 90.8% for the photo-degradation and sonophotodegradation, respectively. Pursuant to the kinetic studies, the kinetics models that govern these processes are leaner with acceptable accuracy.
