Abstract: (1088 Views)
The adsorption of cooking oil and used car oil in wastewater has been investigated by means of graphene nanostructures. The graphene nanostructures have been made by improved Hummers method, the Raman spectroscopy and SEM images. The Raman spectra have been confirmed that graphene nanostructures were few layer graphene (FLG) type. The amount of oil removal has been evaluated based on the reduction of height in a graduated cylinder. The results show that the FLG graphene has a significant adsorbent capability. It can be remove cooking oil and used car oil from wastewater up to 20 and 10 times of its weight, respectively. Also, in order to obtain the better analytical investigation, UV-Vis spectroscopy has been applied by water analyzer, which this test confirms the results.
