Synthesis and Characterization of Modified Walnut Shell Biochar DESCRIPTION:\n\n\nMaaike Parajes1\nSuraj Pochampally1\nFaculty Mentor: Jaeyun Moon, Ph.D.1\n1Howard R. Hughes College of Engineering, Department of Mechanical Engineering\nABSTRACT\nBiochar (BC) is a porous carbon material synthesized from different biomasses that are subjected to pyrolysis. This product is an efficient and eco-friendly alternative to conventional absorbents used for contaminant removal in groundwater systems. In this study, we aimed to develop efficient methods of preparing walnut shell-based biochar through acid, base, and steam modification and compare these modified biochars with the unmodified version. The preparation of biochar involved pyrolysis using an argon gas-filled chamber at a temperature of 900 °C. These BCs were then crushed and sieved to separate the microporous particles. To further evaluate the biochars’ characteristics, it was characterized using SEM, FTIR, EDS, BET, and contact angle measurements. The modification results showed that the modified biochars have different functional groups and are more hydrophilic than the unmodified biochar. Upon further investigation, the results can vastly improve the usage of biochar in the remediation process of contaminants to make the process economically feasible and environmentally friendly.\n URL:https://oursymposium.sites.unlv.edu/program/synthesis-and-characterization-of-modified-walnut-shell-biochar/ ORGANIZER;CN=The Office of Undergraduate Research:MAILTO:our@unlv.edu CATEGORIES:Health & Natural Sciences & Engineering END:VEVENT END:VCALENDAR
