Adsorptive Eradication of Cadmium(II) from Water Using Biocomposites of Polyaniline with Madhuca longifolia and Eugenia jambolana Leaves Powder

摘要

Adsorptive eradication of cadmium(II) from water was studied in batch mode using novel synthesized polyaniline/Madhuca longifolia and polymiline/Eugenia jambolana composites. The optimum conditions of sorption of cadmium(TI) solution with polyanillne/Mad/huca longifolia composite were: 0.6 g/50 mL adsorbent dose, 40 min contact time, 5 pH and 50 °C temperature. Whereas for polyaniline/ Eugenia jambolana composites, these conditions were:adsorbent dose 0.6 g/50 mL, 80 min contact time, 6 pH and 30 °C temperature. Langmuir isotherm model was applicable in both cases, indicating that monolayer chemisorptive removal of metal ions occurred more on homogeneously distributed binding sites of composites as compared to physiosorption on multilayers binding sites.
