Abstract
Water pollution is a critical environmental issue that poses significant threats to aquatic ecosystems. Industrial activities, agricultural runoff, and human sewage are some of the primary sources of water contamination. The resulting polluted water can have devastating effects on aquatic life, including reduced oxygen levels and increased toxicity. Activated carbon, a highly effective adsorbent, is commonly utilized in the treatment of water contaminated with organic pollutants. Biocarbons can be produced through physical or chemical activation processes. The physical activation process involves carbonization of a carbon-rich precursor followed by oxidation of the surface with an activating gas, such as carbon dioxide. Simultaneous occurrence of carbonization and activation is referred to as direct activation. Conversely, chemical activation involves impregnation of the precursor with an activator followed by thermochemical treatment. By optimizing the activation process and selecting the appropriate precursor material and activating agent, activated carbon-based adsorbents can be tailored to meet specific water treatment requirements. The activation process produces a highly porous structure with a large surface area that can adsorb a wide range of pollutants from water. Biocarbon shows promise as a solution for treating contaminated water and protecting aquatic ecosystems. Its high adsorption capacity and selectivity make it an effective tool for removing various pollutants from water, such as organic compounds, heavy metals, and other harmful contaminants. However, the effectiveness of activated carbon depends on several factors, including the properties of the material and the characteristics of the pollutants being treated. In this work biocarbons form fennel seeds (Foeniculum vulgare) were obtained by chemical, physical and direct activation using conventional heating. The physicochemical properties of the obtained carbon materials were studied, and their sorption capacities towards methyl red were checked. The effect of pH and temperature of the aqueous solution of the dye on the sorption capacity was determined, and two models (Langmuir and Freundlich) were used to determine the mechanism of adsorption of the dye on the obtained activated carbons. In addition, the kinetics of adsorption of an aqueous solution of methyl red on the obtained carbon materials was determined.
