Electrochemical Degradation of Crystal Violet Using Ti/Pt/SnO2 Electrode

Abstract: Today, organic wastes (paints, pigments, etc.) are considered to be a major concern for the pollution of aqueous environments. Therefore, it is essential to find new methods to solve this problem. This research was conducted to study the use of electrochemical processes to remove organic pollutants (e.g., crystal violet (CV)) from aqueous solutions. The galvanostatic electrolysis of CV by the use of Ti/Pt/SnO2 anode, were conducted in an electrochemical cell with 100 mL of solution using Na2SO4 and NaCl as sup… Show more

“…88 % in both synthetic water and real wastewater effluent, although the kinetics was faster in the latter case. This might be due to the presence of chloride ions in the real wastewater effluent, which would react with the hydroxyl radicals to produce active chlorine that accelerates the oxidation process [54]. The salinity and moderate COD values of the water matrix (Table 1) do not seem to have a significant impact in the performance of the EF reaction.…”

“…Thus, there is an imperative necessity to evolve a new strategy for CV and RR removal. Although there are several techniques such as electrochemical [9,10], coagulation/flocculation [11,12], biological treatment [13,14], and ozonation [15,16] have been reported for CV and RR treatment. However, most of these techniques are either economically unfavorable or technically complicated which hinder them to be applied in practice.…”

“…‘Wastewater’ is defined as the waters that come out as a result of residential areas, industrial establishments and energy production facilities, agricultural and animal practices and contain biological and chemical impurities that are harmful to the environment. Wastewaters cause environmental pollution by polluting streams, groundwater, lakes and seas (El Brychy et al, 2021).…”
