Abstract
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).
