The objective of this work was to optimize the experimental conditions for biosorption of methylene blue dye using dried
sun flower seed hull as the biosorbent. With this aim, central composite design model was applied to achieve maximum
biosorption capacity q (mg/g). In the model studied, independent variables were pH (2-10), ash dosage (0.05-0.45 g/20 ml), dye
concentration (0.005-0.025 mg/L), and temperature (24.5-54.5 oC). The quadratic model was developed for the predetermined
responses PDR and biosorption capacity and it was clearly seen that the experimental data fit well to model predictions
statistically (R2≥0.79) and Prob>F<0.0001). Experimental conditions for maximum biosorption capacity was determined as
pH 6.0, 0.0169 mg/L MB, 0.244 g DSSH dosage and 39.5 oC temperature.
