Descripción

Aplicación

• Removal of Methylene Blue and Methyl Red from Aqueous Solutions Using Activated Carbons Obtained by Chemical Activation of Caraway Seed.: This study focuses on the removal of methyl red and methylene blue dyes from aqueous solutions using activated carbons derived from caraway seeds. The research highlights the efficiency of these biocarbons in adsorbing the dyes, providing a potential low-cost method for wastewater treatment (Paluch et al., 2023).



• Microporous Biocarbons Derived from Inonotus obliquus Mushroom and Their Application in the Removal of Liquid and Gaseous Impurities.: This paper investigates the use of microporous biocarbons from Inonotus obliquus mushroom for removing impurities, including methyl red, from water and gas streams. The biocarbons demonstrated high adsorption capacities, suggesting their potential in environmental purification applications (Bazan-Wozniak et al., 2022).



• Biocarbons Obtained from Fennel and Caraway Fruits as Adsorbents of Methyl Red Sodium Salt from Water System.: The study explores the effectiveness of biocarbons produced from fennel and caraway fruits in adsorbing methyl red sodium salt from water. It emphasizes the sustainable approach of using agricultural waste to create efficient adsorbents for water treatment (Bazan-Wozniak et al., 2022).
