What is it about?
Congo red (CR), a toxic dye commonly found in industrial wastewater, poses significant environmental and health risks. This study demonstrates, for the first time, that dry green pea husk (DGPH) and its charcoal (CGPH) can serve as cost-effective and eco-friendly adsorbents for CR removal. By optimizing key parameters such as pH, temperature, and adsorbent dosage, we achieved rapid equilibrium adsorption within 30 minutes. The adsorption process was further analyzed using isotherm, kinetic, and thermodynamic models, revealing that DGPH and CGPH follow different adsorption mechanisms. Notably, the process was found to be spontaneous and highly efficient, offering a sustainable solution for water purification. This research highlights the potential of agricultural waste as a viable alternative for tackling water pollution.

Why is it important?
The removal of toxic dyes like Congo red (CR) from wastewater is critical for protecting aquatic ecosystems and human health. This study is important because it demonstrates that dry green pea husk (DGPH) and its charcoal (CGPH) can serve as low-cost, sustainable, and eco-friendly adsorbents for CR removal. Two key findings are that: a) DGPH and CGPH achieve rapid adsorption equilibrium within 30 minutes, making them highly efficient for practical applications, and b) the adsorption process is spontaneous and can be optimized for different temperature conditions, offering flexibility for real-world water treatment scenarios. By transforming agricultural waste into effective adsorbents, this research provides a sustainable solution to water pollution while reducing reliance on expensive and non-renewable materials.
Perspectives
As the lead researcher of this study, I am particularly excited about the potential of this work to bridge the gap between environmental sustainability and practical wastewater treatment solutions. What inspires me most is the idea of transforming agricultural waste—a material often considered useless—into a valuable resource for addressing water pollution. This research not only highlights the effectiveness of dry green pea husk and its charcoal as adsorbents but also underscores the importance of exploring low-cost, eco-friendly alternatives in environmental science. I believe this study opens the door for further exploration of other agricultural byproducts and their applications in pollution control. Personally, seeing how such a simple and sustainable approach can make a meaningful impact on environmental challenges is incredibly rewarding and motivates me to continue working on innovative solutions for a cleaner, greener future.
