Summary of article contents:
Introduction
The extensive use of synthetic dyes in various industrial processes has led to significant water pollution, particularly from industries such as textiles, paper, and cosmetics. Reactive dyes, which provide vibrant colors and good fastness, can be toxic to aquatic life, posing health risks to humans and the environment. Traditional methods of treating dye-laden wastewater are often inadequate due to the synthetic and stable nature of these compounds. This study investigates the use of Scabiosa prolifera (Carmel Daisy) as a biosorbent for the removal of methylene blue dye from wastewater.
Adsorption Mechanism
The study highlights the adsorption process as a highly effective method for dye removal from wastewater. The Carmel Daisy biosorbent shows significant potential due to its natural abundance and low cost. During the experimental phase, various parameters such as dye concentration, contact time, temperature, pH, and adsorbent dosage were analyzed to understand their influence on adsorption efficiency. The results indicate that the adsorption process is influenced by multiple factors, with increasing initial dye concentration leading to a higher adsorption capacity due to greater mass transfer driving forces.
Kinetic and Isotherm Study
Kinetic studies revealed that the adsorption of methylene blue onto Carmel Daisy follows a pseudo-second-order kinetic model, indicating that the rate of adsorption is contingent upon the availability of active sites on the adsorbent rather than the concentration of the dye. Additionally, adsorption isotherm models were applied, and the Freundlich isotherm best fitted the experimental data, suggesting multilayer adsorption on a heterogeneous surface. This indicates that the interaction between the dye molecules and the biosorbent is complex and governed by various physical processes.
Thermodynamic Analysis
The thermodynamic parameters obtained from the study suggest that the adsorption process is exothermic and spontaneous. The negative change in Gibbs free energy indicates that the process occurs naturally without requiring external energy input. This suggests that Carmel Daisy can be effectively used for waste treatment in an environmentally friendly manner, providing a sustainable option for pollutant removal from industrial effluents.
Conclusion
The study successfully demonstrates that Scabiosa prolifera serves as an effective biosorbent for the removal of methylene blue from wastewater. The findings highlight its potential as a low-cost and environmentally friendly alternative for wastewater treatment. The adsorption kinetics, isotherms, and thermodynamic properties underscore the efficiency and suitability of using this natural biosorbent in addressing water pollution challenges associated with synthetic dyes.
