Microstructure Investigation of Activated Carbon Prepared by Carbon Dioxide-Physical Activation

Abstract

Abstract. in this Study, Activated Carbon was Created by Physically Activating Potato Peel Waste (PPW) with Carbon Dioxide. the Potential of this Approach, which Uses Carbon Dioxide to Produce Actuation Carbon (AC) from Precursor Potato Peel Waste, has been Investigated. Utilizing x-Ray Diffraction Analysis, Scanning Electron Microscopy, and Atomic Force Microscopy, the Microstructure of the Activated Carbon was Examined. the Average Crystallite Size was Affected by Employing Varied Periods for the Activation Process, as Seen by the Crystallite Size of the High-Intensity Peaks of the Precursor Potato Peel Waste at Various Drying Times and the Activated Products. after 60 Minutes of Drying, the Activation Stage was under Ideal Conditions, and in Comparison to the other Times, a Size of 325 Nm was Also Attained with the Rest of the Periods, as well as a High Adhesion Elevation Surface Region for the Carbon. the Activated Carbon Produced Using Physical Activation Showed a Surface Area as High as 1733 m2/g with a Pore Volume of 0.45 cm3/g, whereas the Precursor Showed a Surface Area of < 4 m2/g. this Investigation Aims to Modify the Surface of Activated Carbon without Significantly Altering its Structural Parameters for Use in Future Renewable Energy Sources and to Make the Synthesis of such Materials more Potent, more Eco-Friendly, and Less Expensive.

Removal of Toxic Hexavalent Chromium from Wastewater by Activated Carbon Generated from Liming Pelt Trimming with Tannin

“…Recently, surface modified water hyacinth , coconut tree fiber (Kumari et al 2020), poly-aniline coated sugarcane bagasse were employed as an adsorbent to remove Cr(VI). Activated carbon has been widely recognized as an excellent adsorbent for the removal of various contaminants from water and wastewater due to its high surface area, porosity, and adsorptive capacity Jasim et al 2023;Azam et al 2022). A potentially cost-effective replacement adsorbent for the successful removal of Cr(VI) from wastewater is amide-functionalized biochar (Ali et al 2023).…”
