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.
