Descripción
Several industrial sectors, such as textiles, cosmetics, food and pharmaceuticals, use synthetic dyes including crystal violet and methylene blue, among others, which are recognised as persistent pollutants in water bodies due to their resistance to biodegradation. On the other hand, the implementation of agro-industrial waste as low-cost adsorbent materials is making its way towards greener and greener decontamination treatments. The Sustainable Development Goals and the Pact of Amsterdam together with the ISO 59000 Standards seek to contribute to the sustainability of these treatments by incorporating Circular Economy loops within industrial processes. Furthermore, industries like the Moringa infusion producer 'El Moringuero' face the challenge of discarding approximately 80% of their crop, which consists of branch, trunk, and seed husk waste. These companies need effective solutions for managing large volumes of waste material. This study explores the potential connection between these two issues and suggests the feasibility of integrating this process into a Circular Economy framework by utilizing this waste as an adsorbent for crystal violet. The equilibrium test results demonstrated that at temperatures of 10, 20, and 30°C, the experimental data better fit the reundlich model. However, at 40°C, it was not possible to differentiate between the Langmuir and Freundlich models. Regarding kinetic studies, all experimental curves better matched the second-order model. The fit of the experimental data to the Freundlich model and second-order kinetic model confirms that the adsorption process is heterogeneous in nature and likely controlled by chemical mechanisms. As for thermodynamics, the results did not show a direct correlation between the efficiency of the adsorption process and temperature, suggesting that temperature does not play a decisive role in the adsorption capacity of the material studied. In conclusion, the results indicate that lignocellulosic residues from Moringa oleifera are a low-cost, high-efficiency adsorbent material for treating effluents contaminated with industrial dyes like crystal violet.
