ARSENIC AND MOLYBDENUM IONS REMOVAL BY Fe3O4 EMBEDDED ACRYLAMIDE - TRIAZINE HYBRID - POLYMER

Abstract

The synthesized hybrid-polymer was used for the removal of As(V) and Mo(VI) ions from aqueous solution. The treated metal ion solutions were analyzed by inductively coupled plasma-optical emission spectroscopy. The highest removal percentages were obtained at pH 2.5. The effect of time, agitation rate, temperature, initial concentration, and polymer dosage were studied to find optimal removal conditions. The maximum uptake was found to be at 150 min contact time, 150 rpm agitation rate, and 25 degrees C temperature. At the optimal conditions, maximum uptake of As(V) and Mo(VI) ions was found 100% and 98%, respectively by using 0.25 g polymer. The kinetic parameters were calculated by linearized form of pseudo-fist-order and pseudo-second-order models. The results were found to correlate with the pseudo-second-order kinetic model. Also, the results were analyzed by Langmuir and Freundlich isotherms. The equilibrium adsorption data followed the Langmuir isotherm model.
