This study investigates the potential of activated carbon (AC) derived from walnut shell powder as an effective adsorbent for the removal of Reactive Blue 19 (RB 19) dye from aqueous solutions. The textile industry is a significant contributor to water pollution, primarily due to the discharge of synthetic dyes, which pose serious ecological and health risks. The research focuses on optimising the adsorption process by evaluating various parameters, including initial dye concentration and temperature. The AC was characterised using BET surface area analysis, revealing a high surface area of 2854.25 m2/g, which enhances its adsorption capacity. The adsorption kinetics were analysed using multiple models, with the Pseudo Second Order model providing the best fit, indicating that the adsorption rate is primarily dependent on the availability of active sites on the AC surface. Additionally, the study employed various isotherm models, including Langmuir and Freundlich, to describe the adsorption behaviour, confirming the complex nature of the process. The findings highlight the effectiveness of walnut shell-derived AC in wastewater treatment, promoting sustainable practices by utilising agricultural waste for environmental remediation. This research contributes valuable insights into optimising dye removal processes, ultimately supporting efforts to mitigate water pollution and enhance environmental sustainability.
