Descripción

Aplicación

• Adsorptive Removal of Dyes and Contaminants: Activated charcoal is extensively used for the adsorption and removal of dyes and other contaminants from aqueous solutions. Recent research highlights the use of activated charcoal modified with BaFe₁₂O₁₉ powder for the efficient removal of methyl blue dye. This magnetic adsorbent can be easily retrieved and reused, making it a sustainable option for water purification (Polley and Bera, International Journal of Environmental Analytical Chemistry, 2023).


• Heavy Metal Detection and Removal: Activated charcoal is utilized in composite materials for detecting and removing heavy metals from water. A notable study developed a Ni-sensor based on activated charcoal plastic membranes, showcasing the material′s effectiveness in analytical applications for environmental monitoring and pollution control (Zareh et al., Journal of Analytical Chemistry, 2022).


• Filter Composites for Industrial Wastewater Treatment: Activated charcoal combined with banana rachis cellulose nanocrystals has been used to create filter composites for industrial wastewater treatment. These composites effectively remove dyes and heavy metals, demonstrating their potential for large-scale environmental applications and enhancing water quality (Rahman et al., International Journal of Environmental Analytical Chemistry, 2022).


• Dental Applications: In dental research, activated charcoal combined with calcium hydroxide has been evaluated for its effect on dentin microhardness. This combination shows promise in dental treatments, particularly in enhancing the mechanical properties of dentin and offering potential benefits in restorative dentistry (Abdel Hamid, Egyptian Dental Journal, 2023).


• Environmental Adsorbents and Sensors: Activated charcoal is also used in creating advanced environmental adsorbents and sensors. For instance, a study focused on the development of magnetically retrievable BaFe₁₂O₁₉-activated charcoal-chitosan composite powders for the adsorption of methyl blue dye. These materials offer high efficiency, reusability, and easy recovery, making them ideal for environmental remediation applications (Polley and Bera, International Journal of Environmental Analytical Chemistry, 2022).
