In this study, we used a synthesized cross-linked magnetic chitosan with graphene oxide
beads to study the removal of perchlorate from wastewater. The prepared complex was
characterized using transmission electron microscopy (TEM), Fourier Transformation
Infrared spectroscopy (FT-IR), vibrating sample magnetometry (VSM) and Thermal
gravimetric analysis (TGA).
Several parameters were studied including the effect of pH, contact time and the coexisting
anions. The study showed that the adsorption could be study in a wide range of
pH. The study showed that the adsorption follows a pseudo-second order model and
Langmuir adsorption isotherm. The enthalpy and negative Gibbs standard free energy
showed that the adsorption process was exothermic and spontaneous. The perchlorate
adsorbent can be regenerated well by 0.1% NaCl solution.
