This research is focused on the adsorption of Acid Black 26 dye from aqueous solutions using zeolite as an adsorbent. The experiments were designed by response surface methodology. Quadratic model was used to predict the variables. Analysis of variance was used for investigation of variables and interaction between them. The highest removal percent (87.98%) was attained, and the optimum parameters are achieved: zeolite amount (0.55 g), dye concentration (25.78 mg L-1), pH = 4, and time (59.99 min). F value (329.44), P value (< 0.0001), the adequate precision (66.04), non-significant lack of fit, and R-2 = 0.9970 demonstrate a good correlation between experimental and predicted data.
