摘要

Matured flamboyant pods (FBP) activated with ZnCl 2 were used for batch adsorption ofBromophenol blue (BPB) dye under the effects of concentration (10-200 ppm), contact time (20-300 min), biosorbent dosage (20-120 mg) and particle size (300-850 μm). The data obtained werefitted to Langmuir and Freundlich isotherm models as well as pseudo-first-order (PFO), pseudo-second-order (PSO) and Elovich kinetic models. The highest adsorption capacity and removal efficiency of 7.5762 mg/g and 75.76%, respectively, were obtained under the effects of initial dyeconcentrations. The correlation coefficient (R 2 ) for the Langmuir and Freundlich isotherms are inthe range 0.9938-0.9979 and 0.9895-0.9953, respectively, while, R 2 , in the ranges 0.5931-0.815,0.9962-1.000 and 0.8046-0.8828, were obtained for the PFO, PSO, and Elovich kinetic models,respectively. The order of fit of the kinetic models is PSO > Elovich > PFO. The study suggestsflamboyant pod as promising biomass for the remediation of dye-bearing industrial effluents.
