Chemical Impregnation Methods Optimized For Spent Activated Carbon Regeneration

One efficient method for recovering the adsorptive capacity of spent activated carbon is to regenerate itthrough chemical impregnation. To regenerate the carbon and eliminate adsorbed pollutants, the spent activatedcarbon is treated with specific chemicals. The purpose of this study was to examine the properties of the regeneratedactivated carbon to determine whether it might be used in water purification applications. Spent activated carbonwas gathered from the water purification unit's spent activated carbon cartridge. It is easily accessible and containsmore carbon. At the ideal activation period, 1N KOH was used to activate the wasted carbon. The elemental analysisof spent activated carbon both before and after activation is the focus of this work. Scanning Electron Microscope(SEM), CHNS (elemental analysis), and significant index iodine number studies were used in this work. The goal ofthe current project is to investigate the regeneration of spent activated carbon. Regenerated carbon has been foundto have well-developed pores and activation sites.
