Abstract: The use of Congo red dye in the textile, is a source of pollution. In this study, the adsorption removal of walnut shell powder as a bio-adsorbent for Congo red dye was evaluated. The surface of the adsorbent was characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), energy dispersive X-ray (EDX), X-ray diffraction (XRD), surface area determination (BET), and pH point of zero charge (pHpzc). Four factors affecting the dye adsorption process were studied including pH, initial dye concentration, adsorbent dose, and contact time. The optimization study was conducted using the response surface methodology (RSM) by using the Box-Behnken design (BBD). The results showed that the highest dye removal percentage was 83% with operating conditions of pH 2, an initial dye concentration of 25 mg/L, an adsorbent dose of 1 gram/100 mL, and a contact time of 90 minutes. Meanwhile, the dye removal percentage predicted by RSM was 85% with pH 2, an initial dye concentration of 31.32%, an adsorbent dose of 1 g/100 ml, and a contact time of 92.47 minutes. The Langmuir and Freundlich models were applied to the experimental data. The results of the isotherm study showed that the adsorption conforms to the Langmuir equation with a value of adsorption capacity qmax = 35.11 mg/g. The kinetics of dye adsorption on the surface of walnut shells were studied by applying the pseudo-first-order model and the pseudo-second-order model. The results showed that the adsorption follows the pseudo-second-order model with R2 = 99.9. To increase the adsorption capacity of the walnut shell powder, the surface was modified in two ways: The first one was to convert the shells to nano diameter by grinding. while the second method was to prepare the activated carbon. Both methods gave high removal rates under the worst conditions obtained when using the material in its raw form, which were 92% and 98%, respectively. This study showed that the walnut shell is an effective absorbent material. It is economical to remove Congo red dye from water contaminated with this dye.
