Electrochemical Degradation of Methylene Blue using Ce(IV) Ionic Mediator in the Presence of Ag(I) Ion Catalyst for Environmental Remediation
نویسندگان
چکیده
Methylene blue (MB) is often used in textile industries and actively present the wastewater runs-off. Recently, mediated electrochemical oxidation (MEO) offers a fast, reliable promising results for environmental remediation. Thus, we aimed to evaluate electro-degradation potential of MB by MEO using Ce(IV) ionic mediator. Furthermore, also observed influence addition Ag(I) ion catalyst degradation MB. The was evaluated cyclic voltammetry technique confirmed UV-Vis spectrophotometry, high performance liquid chromatography (HPLC) analysis back-titration analysis. showed that absence catalyst, about 89 % decolorized within 30 min. When 2 mM applied, increased maximum value 100%. spectrum as suggested decreased absorbance at λ 668 nm from 2.125 0.059. HPLC formation five new peaks retention time 1.331, 1.495, 1.757, 1.908, 2.017 min, confirming 52.9% CO2 produced during MEO. More importantly, more than 97% mediator were recovered our investigation. Our improve runs-off quality well other containing methylene blue.

Efficient Fenton like degradation of Methylene blue in aqueous solution by using Fe3O4 nanoparticles as catalyst
Fe3O4 nanoparticles were prepared hydrothermally and characterized by X-Ray diffraction spectroscopy (XRD), and scanning electron microscopy (SEM). It was found that these nanoparticles can act as an efficient catalyst in the degradation of Methylene blue dye in aqueous solution in a Fenton like system in presence of 30% perhydrol. Uv-Vis spectroscopy was used to determine the concentration of ...

Testing the suitability of metallic iron for environmental remediation: Discoloration of methylene blue in column studies
A new method to correlate intrinsic reactivity and treatability efficiency of metallic iron (Fe) was evaluated. A 2.0 mg L methylene blue (MB) solution was used in gravity fed column experiments. The intrinsic reactivity of nine Fe materials (ten samples) was characterized using the EDTA test. Three commercial Fe materials ZVI1 (0.40 0.80 mm), ZVI9 (0.50 mm) and ZVI10 (0.45 0.55 mm) were tested...
