Abstract

Lead (II)-laden wastewater from lead acid battery and printed wire board industries are hazardous to human health and environment due to their toxicity and persistent characteristics. This study focuses on ecofriendly industrial Lutjanus erythropterus fish bone meal waste as biosorbent for Lead (II) removal. In this study, the effects of optimization of biosorption, isotherm, kinetic, thermodynamic, characterization of biosorbent were investigated, and the characteristics of biosorbent were compared with those of commercial resins. The half saturation removal of biosorbent amount was determined at 0.09 g in order to represent the excessive metal in real industrial wastewater condition compared to biosorbent and to minimize the consumption of chemicals and biosorption operation time. Such approach is supported by optimization results and Langmuir isotherm. Results obtained were better with Freundlich than with Langmuir isotherm, confirming the presence of heterogeneous monolayer with reversible binding sites. The biosorption mean energy inferred that chemisorption occurred in Lead (II) biosorption, and pseudo-second-order kinetics implied that chemisorption mechanism is the rate-limiting factor.
