Degradation of textile azo dye solutions containing Methyl Orange by anodic oxidation using an electrochemical reactor was studied. The combined effect of independent parameters (current intensity, initial pH and electrolysis time) on color removal efficiency was investigated and optimized using response surface methodology. A Box-Behnken design was successfully employed for experimental design. The obtained quadratic model was statistically tested using analysis of variance (ANOVA). Results showed that the optimal operating conditions to achieve 98.51% efficiency for color removal were current intensity = 4.6 A, initial pH= 4 and electrolysis time = 65 min, at a dye concentration and temperature of 50 mg/L and 25 °C, respectively.
In Morocco, the quality of water gathered in dams is deteriorating considerably due to different sources of pollution. One of the consequences of this situation is the presence of nutrients , particularly phosphorus and nitrogen, in the water. This, however, indicates an advanced state of eutrophisation of waters. This phenomenon causes an imbalance in the ecosystem with an anarchic development of seaweeds and an intense consumption of oxygen at the bottom of lakes. The present study aims to present the results of the optimization of the choice of the pumping area of the waters of the BAB LOUTA dam in TAZA region, Morocco. This dam is the dam that provides the city of TAZA with drinking water. The results of physico-chemical analyses (dissolved Oxygen, Turbidity, Manganese, pH, and the temperature) were taken according to a vertical deep profile for a duration that spreads from
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
