Equilibrium modeling of the adsorptive eradication of Safranin-O dye from aqueous solutions using the oxalic acid-treated peanut husk as an upcycled agro-waste
In this study, oxalic acid-treated peanut husk (ATPH) was prepared and evaluated as a low-cost biosorbent for the removal of Safranin-O dye from aqueous solutions. Batch adsorption experiments were performed to investigate the effects of pH, adsorbent dosage, contact time, temperature, and agitation speed. The maximum...
