Abstract
The aim of the present study was to assess the performance of the biowaste materials to recover lanthanum (III) from aqueous solution. The biosorbents from animal origin viz., crab shell (CRS), prawn carapace (PC), fish scales (FS), egg shell (ES) and plant origin viz. Neem sawdust (NS), corn style (CS), pineapple crown (PAC), orange peel (OP) were chosen and the influence of various factors viz. pH, contact time, biomass dosage and initial metal concentration on lanthanum (III) sorption were investigated under batch mode. The experimental isotherm data were analyzed using Langmuir and Freundlich model to characterize the adsorption process. The adsorption capacities of CRS, PC, FS, ES were found to be 90.9, 200.0, 250.0 and 100.0 mg/g whereas 166.6, 76.9, 100.0 and 125.0 mg/g for NS, CS, PAC and OP respectively. Langmuir model found to be the best fit for FS and Freundlich model for NS respectively. FS and NS can be used as potential biosorbents for La(III) recovery from aqueous environment.
