Synthesis and characterization of Fe2O3–ZnO–ZnFe2O4/carbon nanocomposite and its application to removal of bromophenol blue dye using ultrasonic assisted method: Optimization by response surface methodology and genetic algorithm

Tunable auto-combustion preparation of TiO2nanostructures as efficient adsorbents for the removal of an anionic textile dye

“…Furthermore, the thermodynamic constants can provide information on the energy changes associated with the adsorption process. Therefore, some thermodynamic parameters have been estimated including the enthalpy change (DH 0 ), entropy change (DS 0 ), and Gibbs free energy change (DG 0 ) through using eqn (13) and (14). 20 ln…”

“…Therefore, several methods have been suggested for this purpose such as membrane separation, coagulation, ultra-sonication, photocatalysis, ozonation, biological treatment, and adsorption. [7][8][9][10][11][12][13][14] Among these methods, adsorption was considered to be one of the most efficient techniques for the removal of non-biodegradable contaminants from wastewater owing to its simplicity in operation, high efficiency, economic applicability, scalability, and the availability of numerous adsorbents. 15,16 In this vein, various adsorbent materials including natural and synthesized polymers, zeolites, activated carbons, hydrotalcites, and clays have been proposed for treatment of wastewater from textile dyes.…”

Elaboration of novel adsorbent from Moroccan oil shale using Plackett–Burman design

“…Statistical analysis of the model was performed to evaluate the analysis of variance (ANOVA). Analysis includes Fisher test (F-test), its associated probability P (F) and the coefficient of determination (R 2 ) which measure the goodness of fit of the regression model (Mohammadzadeh et al, 2016;Rhazi et al, 2015). JMP 7, USA software was used for designing experiments as well as for regression analysis of the experimental data obtained (Dayana Priyadharshini and Bakthavatsalam, 2016).…”

Multi‐responses optimization of simultaneous adsorption of methylene blue and malachite green dyes in binary aqueous system onto Ni:FeO(OH)‐NWs‐AC using experimental design: derivative spectrophotometry method

“…RSM is extensively employed to improve the conditions used in the batch process for dye removal from wastewater and provide fewer numbers of experimental runs to the evaluation of the effects of several factors and their interactions on system response …”
