Environmental Protection by the Adsorptive Elimination of Basic Violet 3 Dye from Water

Various industries generate effluent that contains persistent pollutants, including dyes, which have detrimental impacts on the environment and human health. Underscore the need for eco-friendly materials to treat dye-containing wastewater and prevent adverse effects on water resources. This study focuses on the potential of using pine tree bark (PTB) as an adsorbent to remove hazardous basic violet 3 dye (BV3) from synthetic water. The study examines factors such as contact time, PTB mass, pH and initial BV3 concentration to understand their impact on batch-mode adsorption. The efficiency of PTB for BV3 dye removal is evaluated through a wide range of basic violet 3 dye (BV3) concentrations (15–150 mg/L), pH values (2–10), and temperatures (25–55 °C), with the kinetics and adsorption isotherms of dyes studied systematically. The kinetic and isotherm study shows that the pseudo-second-order kinetic and Freundlich isotherm models accurately describe the experimental data. Based on these findings, it can be concluded that pine tree bark (PTB) is a cost-effective, eco-friendly, and promising material for removing dye molecules from aqueous solutions. This material can effectively mitigate the adverse effects of dye-containing wastewater on the environment and water resources.
