Novel crosslinked and zeolite-filled polyvinyl alcohol membrane adsorbents for dye removal

Novel crosslinked and zeolite-filled polyvinyl alcohol membrane adsorbents for dye removal In order to enhance adsorption capacity for dye removal, mixed matrix SAPO-34/polyvinyl alcohol membrane adsorbent (MMMA) was synthesized. Mixing PVA with SAPO-34 particles provides an effective structure that leads to efficient adsorption performance and high methylene blue removal efficiency. The effect of zeolite content was also studied via synthesis of different MMMAs. Morphology and intermolecular interaction of the MMMAs were determined using fourier transform infrared and scanning electron microscope. The adsorption measurements were carried out in batch mode at various operating parameters such as contact time, temperature, pH, and initial concentration to determine the optimum experimental condition. The experimental data were closely fitted with the Freundlich adsorption isotherm model rather than the Langmuir and the Temkin isotherm models and the adsorption kinetic data were fitted in accordance with the pseudo-second-order model. The evaluated data for ΔG° indicated that the adsorption process is spontaneous at lower temperature values and non-spontaneous at higher temperature values. Estimated ΔH° and ΔS° values also exhibited an exothermic adsorption process with an increase in orderliness at the solid–solution interface. Research on Chemical Intermediates Springer Journals
