Abstract
The adsorption of simulated aqueous solution containing textile remazol reactive dye, namely Red 3BS by palm shell activated carbon (PSAC) as adsorbent was carried out using Response Surface Methodology (RSM). A Box-Behnken design in three most important operating variables; initial dye concentration, dosage of adsorbent and speed of impeller was employed for experimental design and optimization of results. The significance of independent variables and their interactions were tested by means of the analysis of variance (ANOVA) with 95 confidence limits. Model indicated that with the increasing of dosage and speed give the result of removal up to 90 with the capacity uptake more than 7 mg/g. High regression coefficient between the variables and the response (R-Sq = 93.9) showed of good evaluation of experimental data by polynomial regression model.
