This study was undertaken to investigate response surface methodology (RSM) for the removal of methylene blue (MB) from aqueous solution using zinc oxide as adsorbent. The effect of various process parameters namely initial concentration (10–100 mg L-1), adsorbent dose (0.05–0.40 g), time (60–240), pH (7) and stirring rate (150 rpm) was taken as parameter. A total of 15 adsorption experimental runs were carried out using the detailed conditions designed by RSM based on the Box–Behnken design (BBD). The regression co-efficient (R2) of the models developed and the results of validation experiments conducted at optimal conditions strongly suggests that the predicted values are in good agreement with experimental results Regression analysis showed good fit of the experimental data to the second-order polynomial model with coefficient of determination (R2) value of 0.9760 and model F value of 40.68. The predicted R2 value is 0.7979.
