    Application of Response Surface Methodology (RSM) for Crystal violet dye removal from aqueous solution using modified adsorbents

    In this study, biomass wastes were used as alternative precursors for producing high surface area biosorbent (referred to as MM1 and MM2) using chimical activation. The adsorption characteristics of modified biosorbent 1 and modified biosorbent 2 were studied by investigating the removal of a model cationic dye (crystal violet, CV). To optimize important adsorption variables (initial CV concentration, pH, temperature and biosorbent dose), the numerical desirability function of the Box-Behnken Design (BBD) and Central Composite Design (CCD) were used. The numerical desirability function of the Box-Behnken Design and Central Composite Design were used to optimize important adsorption variables (A: initial CV concentration (5–100 mg/L) ; B : pH (2-10) ; C : temperture (20-60) and D: biosorbent dose (0.025-0.2 g).
