The Effect of Non-Thermal Plasma on Graphene Oxide Adsorption of Cadmium

Water pollution is a major concern and these days heavy metals removal is a challenging work# adsorption is one of the most efficient techniques for removing noxious heavy metals from the solvent phase# this study aims the novel application of non-thermal plasma treatment to improve graphene oxide (go) adsorption capacity by increasing oxygen functional groups# it was examined by using oxygen, air and nitrogen gas in cadmium removal# results indicate that the plasma treated go by oxygen gas has increased the adsorption capacity by 7#8%# the cadmium removal was maximum (99#06%) at gas pressure 0#45 mbar, power supply 100 watt and plasma processing time 4 minutes#
