Alginate-Based Hydrogel Beads as a Biocompatible and Efficient Adsorbent for Dye Removal from Aqueous Solutions Safoura Asadi Setareh Eris Saeid Azizian 10.1021/acsomega.8b02498.s001 https://acs.figshare.com/articles/journal_contribution/Alginate-Based_Hydrogel_Beads_as_a_Biocompatible_and_Efficient_Adsorbent_for_Dye_Removal_from_Aqueous_Solutions/7321064 In this study, sodium alginate was employed as a starting material for preparing two kinds of biocompatible adsorbents, including calcium alginate hydrogel beads and magnetic hydrogel beads. Fourier transform infrared spectroscopy, X-ray diffraction pattern, and scanning electron microscopy/energy-dispersive X-ray techniques were used to characterize the prepared adsorbents. The performance of the prepared adsorbents for the removal of methyl violet from aqueous solution was studied in detail. Both kinetics and equilibrium aspects of methyl violet adsorption were investigated, and the obtained equilibrium and kinetics data were described with various adsorption models. The effects of initial dye concentration, adsorbent dosage, and temperature on adsorption performance were investigated. Thermodynamic parameters of adsorption were obtained as well. 2018-11-09 09:13:24 Thermodynamic parameters biocompatible adsorbents adsorption performance sodium alginate Aqueous Solutions methyl violet adsorption Efficient Adsorbent adsorption models Alginate-Based Hydrogel Beads hydrogel beads equilibrium aspects Dye Removal dye concentration calcium alginate hydrogel beads X-ray diffraction pattern methyl violet kinetics data adsorbent dosage
