| dc.description.abstract | One of an emerging trace contaminants is perchlorate that has been detected in surface water, ground water, soil and food globally. Cross linked Magnetic Chitosan / Graphene Oxide Beads (CM/GO Bs) were synthesized and tested to remove perchlorate anions from waste water. The complex was characterized by transmission electron microscopy, Fourier Transformation Infrared spectroscopy and vibrating sample magnetometry. The effect of pH, contact time, co-existing anions and temperature on adsorption was investigated. Particles could be recovered easily by external magnetic field because they were super-paramagnetic. The CM/GO Bs complex could adsorb perchlorate in a wide range of pH from 4 to 10 . Co-existing anions may inhibit the adsorption of perchlorate on CM/GO Bs. Kinetic data were well fitted to the pseudo-second-order model. The enthalpy and negative gibbs standard free energy show that the adsorption process was exothermic and spontaneous. the exhausted adsorbent can be regenerated well by 0.1% NaCl solution. | en_US |
