NOVEL SOLID PHASE-EXTRACTOR BASED ON FUNCTIONALIZATION OF SILICA FUME WITH 8-HYDROXYQUINOLINE FOR DETERMINATION OF Pb(II) IN WATER SAMPLES BY SQUARE-WAVE ADSORPTIVE STRIPPING VOLTAMMETRY
A solid phase was developed by the fictionalization of silica fume with 8- hydroxyquinoline (SF-8HQ) through microwave-assisted solvent-free synthesis process for separation, removal and determination of Pb(II) in aqueous solutions. SF-8HQ was characterized by FTIR, XRD and SEM. The experimental con...

| description | A solid phase was developed by the fictionalization of silica fume with 8- hydroxyquinoline (SF-8HQ) through microwave-assisted solvent-free synthesis process for separation, removal and determination of Pb(II) in aqueous solutions. SF-8HQ was characterized by FTIR, XRD and SEM. The experimental conditions such as pH, shaking time, weight of sorbent and concentration of Pb(II) were optimized. It was found that SF-8HQ showed higher percentage of extraction (100.0 %) for Pb(II) and adsorption capacity value (171.55 mg g –1 ). The sorption kinetic data of Pb(II) on SF-8HQ was fitted to pseudo-second-order (r2 = 1). Moreover, the adsorption isotherm data for adsorption of Pb(II) was fitted to Langmuir and Freundlish isotherm models (r2 = 1). Breakthrough curves were analyzed at different bed heights as well as flow rates using fixed bed column. The practical applicability of SF-8HQ was examined to determine a trace amounts of Pb(II) in environmental water samples with high recovery values. |
