摘要

This present study synthesizes and characterizes adsorbents from organic waste components as prospective substrates for sequestering carbon under normal circumstances. Three excessively attainable and affordable resources, including (a) peanut shell (PS), (b) wheat straw (WS), and (c) cotton stalk (CS), are utilized to produce activated carbons by applying a single-phase activation. Distinctive characterization and analytical methods, including (i) quantitative and elemental analyses, (ii) Brunauer–Emmett–Teller (BET)-surface area and Barrett, Joyner, and Halenda (BJH)-pore size distribution analyses, (iii) surface morphological and topographical analyses, (iv) surface functional groups analysis and (v) thermal stability analysis is employed to evaluate their surface textures and physical and chemical properties of activated carbon samples. The highest adsorption capacity of the adsorbent samples is examined at various possible conditions. The important adsorption parameters of the adsorbent samples are identified and presented in detail. The tested samples’ outcomes revealed that adsorbents would be efficient for CO2 capture.
