Investigation of Adsorption Properties of Agro-Waste-Derived Activated Carbons Prepared via Various Physicochemical Activation Methods for Gasoline, Iodine, and Methylene Blue

Activated carbons (AC) have been effectively produced from rice husk using the following activation methods: i) physical activation; ii) chemical activation. We prepared ACs using CO₂ gas as an activator under various activation temperatures for a time period of 1 hour. This study investigated the fabrication of activated carbon (AC) from rice husk using a chemical activation method that used H₃PO₄, KOH, and ZnCl₂. This study looked at how to make activated carbon (AC) from rice husk utilizing a chemical activation technique that included H₃PO₄, KOH, and ZnCl₂.The influence of several parameters, for instance carbonization temperature, carbonization duration and concentrations, on ACs BET surface area was investigated. Rice husk activated carbons (RHAC) were described by thermo-gravimetric investigation (TGA), Scanning Electron microscopy (SEM), Brunauer Emmett Teller (BET) surface and N₂ adsorption. Both techniques of activating activated carbon have high adsorption characteristics. During this, adsorption parameters for utilizing the GC-MS method to analyze gasoline. The agricultural wastes employed in the study have been demonstrated to be possible precursors for the cost-effective on-site generation of activated carbon, thereby easing the problem of agricultural waste management.
