Electrochemical Modification Of Granular Activated Carbon And Carbon Nanofibers To Determine Effect On Adsorption, Jose E. Martinez Sanchez
Electrochemical Modification Of Granular Activated Carbon And Carbon Nanofibers To Determine Effect On Adsorption, Jose E. Martinez Sanchez
Theses and Dissertations
Granular activated carbon and carbon nanofiber samples were tested as is and electrochemically modified to determine the effect on adsorption. An electrochemical cell was used to modify the carbon samples. The samples were then used in bench bottle tests with 2,4-dinitrotoluene (DNT), brilliant blue (BB) dye, and methylene blue (MB) dye solutions and sampled over time intervals. An ultraviolet–visible spectrophotometer was used to analyze the results of the bottle bench tests. The results indicated that electrochemically modified coal-based carbons’ adsorption were improved 25% over the adsorption of the as is carbon samples prior to modification. The electrochemical modification increased adsorption …
