Preparation and characterization of activated carbon from groundnut and egg shells as viable precursors for adsorption

This study was carried out to prepare groundnut shell (GS) and eggshell (ES) into activated carbon (AC) characterize the AC using Association of Official Analytical Chemists (AOAC) American Standard for Testing Materials (ASTM) methods. The produced characterized for: pH, moisture content, volatile matter, ash fixed carbon, bulk density surface area. Surface functional groups morphology were also determined Fourier Transformed Infrared (FT-IR) Scanning Electron Microscope (SEM) respectively. ranges following results achieved biomasses: Groundnut Activated Carbon (GSAC) Eggshell (ESAC) respectively: pH (6.80±0.101−7.80±0.011); content (14.10±0.101−12.90±.110%); matter (9.20±0.112−9.90±0.012%); (8.98±0.111−5.80±0.111%); (67.70±0.010−71.40±110%); (370.00±0.000−380.00−0.000 g/L); area (880.00±0.100−800.00±0.000 m2/g). agro-wastes have high contents low inorganic which make them viable adsorbents. FT-IR analysis revealed presence oxygen complexes such as carbonyls OH on ACs in addition good pore structures from SEM studies that could be precursors production. overall showed can optimally used effective adsorbents, thereby ensuring cheaper, readily available affordable treatment effluent, waste water oils.
