Abstract

This article presents a method for producing activated carbon adsorbents from walnut biomass and rice husks using chemical activation with KOH. Carbonization and thermochemical activation were studied at various temperatures (500–900°C), and the material balance, gas composition, and adsorption characteristics of the resulting materials were assessed. SEM and TEM analyses confirmed the formation of a meso- and microporous structure with a high specific pore volume and significant surface area. The resulting adsorbents demonstrated high efficiency in removing organic matter, suspended particles, and BOD from wastewater, especially for samples with KOH (1:4 ratio). The results demonstrate the potential of using agro-industrial waste to produce highly effective sorbents in an environmentally friendly manner.
