Document Abstract
Glycine functionalized magnetic nanoparticle entrapped calcium alginate beads (GFMNPECABs) were
successfully prepared and used as a novel adsorbent for removal of Cu(II). The adsorbent was
characterized by Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS)
measurements, scanning electron microscopy (SEM), x-ray diffraction (XRD) and Brunauer-Emmett-
Teller (BET) surface area analysis. Magnetic nanoparticles (MNPs) could be successfully functionalized by
glycine and glycine functionalized magnetic nanoparticles (GFMNPs) could be entrapped into the
alginate biopolymer. BET result showed specific high surface area and mesoporous structure of the
adsorbent. The adsorption capacity of GFMNPECABs for Cu(II) ions evaluated by batch adsorption
experiments showed maximum value of 120 mg/g at pH 6 in 160 min. Adsorption isotherms well
fitted to
different available models and data could be best described by Langmuir model. The adsorption kinetics
followed pseudo second order model well. The thermodynamic studies showed exothermic and
spontaneous nature of Cu(II) adsorption
