A Novel Biochar Approach: Valorization of Wildfire Residual for The Removal of Cationic Dye from Textile Wastewater
Objective: The main objective of this study was to reveal the cationic dye (methylene blue) removal performance of activated biochar materials produced from the pine tree (Pinus brutia) wildfire remnants from 2024 Çanakkale Wildfire area.
Materials and Methods: The pine tree (Pinus brutia) wildfire remnant samples were collected from the 2024 Çanakkale Wildfire area. Boric acid and Sodium Hydroxide were used as activation agents on the samples. Then, methylene blue adsorption equilibrium and kinetic studies were conducted to reveal the adsorption performance of the produced biochar adsorbent. The adsorption capacity, adsorption isotherms, and kinetic study experiments were conducted.
Results: The results showed that the Langmuir adsorption isotherm fitted very well with the Sodium Hydroxideactivated biochar samples for the methylene blue adsorption equilibrium experiments. The Methylene Blue Removal percentage of % 96 was reached. The kinetic studies revealed that the pseudo-second-order kinetic model fitted the experimental data well.
Conclusion: The adsorption capacity and percent methylene blue removal performances indicated that the produced activated carbons have competitive adsorption potentials in relation to the literature data.
