Cross-linked chitosan-epichlorohydrin beads (CEB) was prepared and studied for the removal of Reactive Red 4 (RR4) from textile industry. The effect of parameters such as adsorbent dosage (A: 0.5-1.5 g/L), pH (B: 4-10) and time of contact (C: 30-80 min) on the color removal of RR4 was investigated using response surface methodology (RSM) based on Box–Behnken surface statistical design at an initial RR4 concentration, Co = 100 mg/L as a fixed input parameter. The results of RSM indicated that the proposed model predicted the responses adequately within the limits of input parameters being used. Regression analysis showed good fit of the experimental data to the second-order polynomial model with coefficient of determination (R2) value of 0.9958 and Fisher F-value of 185.36. Optimization of adsorbent dose (1.0 g/L), pH (4.0), and contact time (80 min) gave a maximum of 70.53% RR4 removal by CEB.
