Assessment of Advanced Oxidation Processes Using Zebrafish in a Non-Forced Exposure System: A Proof of Concept

“…After this time, the reaction was stopped by the addition of enough NaOH 1 M to reach a pH value of 12.0. Under this alkaline condition, the remaining H 2 O 2 degraded and iron precipitated as a hydroxide [43]. The alkaline mixture stayed still for 10 min, and the liquid supernatant was separated and then treated with H 2 SO 4 1 M to reach a pH value of 7.0.…”

Electrodialysis applied to the removal of iron ions in an aqueous solution

“…The methods for removing metals, including iron, are not new and are very varied, being able to use processes such as ion exchange, adsorption, oxidation, membrane processes, electrochemical processes, coagulation-flocculation (Abdulhadi et al, 2020;Aragaw, 2020;Dyer et al, 2012;Laverde-Cerda et al, 2019;Torbaghan and Khalili Torghabeh, 2019). Of these processes, the electrochemical and membrane methods attract attention (Torres-Santillan et al, 2019), since they have the advantage of not requiring the addition of alkalizing reagents, mentioned above, during the process that can lead to another type of pollution (mainly generation of sludges containing heavy metals), both processes converge in a process known as electrodialysis, this it has the particularity of separating the ions that are present in an aqueous solution (Baker, 2012).…”
