The aim of the present work was to utilize agriculture waste biomass for the development of low-cost material and find its application for the treatment of colored water and wastewater. In the current study, the potential of Pterospermum acerifolium leaves (agriculture waste biomass) as novel, efficient and cost-effective adsorbent for the removal of industrially important dye bromophenol blue (BPB) from aqueous solutions was investigated. The newly developed adsorbent was characterized using various analytical techniques such as FT-IR, EDX, SEM and BET surface area. The PZCpH was also determined and found to be 5.40. In a batch adsorption system, the effect of various operating parameters such as equilibrium time, amount of adsorbent, pH, temperature, adsorbent particle size and adsorbate concentration were studied. In order to understand the mechanism of adsorption, the well-known adsorption kinetics, equilibrium and thermodynamics models were applied. The current study revealed that the newly developed adsorbent (P. acerifolium leaves) can be used as potential low-cost solid medium for the removal of industrially important dye (BPB) and can be applied for the treatment of colored water and wastewater.
