dc.description.abstract | This study examines the adsorption isotherms, kinetics and mechanisms of Pb2+ sorption onto waste cow bone powder (WCBP) surfaces. The concentrations of Pb2+ in the study range from 10 to 90 mg/L. Although the sorption data follow the Langmuir and Freundlich isotherm, a detailed examination reveals that surface sorption or complexation and co-precipitation are the most important mechanisms, along with possibly ion exchange and solid diffusion also contributing to the overall sorption process. The co-precipitation of Pb2+ with the calcium hydroxyapatite (Ca-HAP) is implied by significant changes in Ca2+ and PO4 (3-) concentrations during the metal sorption processes. The Pb2+ sorption onto the WCBP surface by metal complexation with surface functional groups such as a parts per thousand POH. The major metal surface species are likely to be a parts per thousand POPb+. The sorption isotherm results indicated that Pb2+ sorption onto the Langmuir and Freundlich constant q (max) and K (F) is 9.52 and 8.18 mg g(-1), respectively. Sorption kinetics results indicated that Pb2+ sorption onto WCBP was pseudo-second-order rate constants K (2) was 1.12 g mg(-1) h(-1). The main mechanism is adsorption or surface complexation (a parts per thousand POPb+: 61.6%), co-precipitation or ion exchange [Ca-3.93 Pb-1.07 (PO4)(3) (OH): 21.4%] and other precipitation [Pb 50 mg L-1 and natural pH: 17%). Sorption isotherms showed that WCBP has a much higher Pb2+ removal rate in an aqueous solution; the greater capability of WCBP to remove aqueous Pb2+ indicates its potential as another promising way to remediate Pb2+-contaminated media. | - |
