In the present study, activated walnut shell powder (AWP) was fabricated by chemical modification of waste walnut shell using sulphuric acid activation method. The AWP formed was analyzed under different sets of batch experiments to observe the adsorption characteristics on brilliant yellow (BY) dye. Influence of different parameters such as BY concentration, amount of dose, pH and contact time was observed and optimum conditions has been calculated. Various characterization techniques SEM, BET, FTIR were applied to understand morphology, surface area and presence of various functional groups on the adsorbent. The interaction between adsorbate and adsorbent was further investigated by applying Langmuir, Freundlich and Temkin Isotherms where Langmuir shows best suitability with regression coefficient > 0.9. Maximum removal efficiency accounted for 90% under optimized parameters. This work offers an ecofriendly and economic removal of Industrial dye BY using AWP adsorbent
