Optimized preparation of activated carbon from municipal sewage sludge and application to the adsorption of azo dye from aqueous solutions

In this study, the conditions for preparation of active carbon from municipal sewage sludge (MSS) were optimized from application to the efficient removal of the azo dye, Acid Orange 7 (AO7), from aqueous solutions. To maximize the adsorption capacity (response variable) of the MSS‐derived activated...
