Descripción
The persistence, toxicity, and low biodegradability of synthetic dyes in aquatic systems constitute a relevant environmental challenge. This study evaluated the adsorption of crystal violet (CV) in aqueous solution using Moringa oleífera trunk waste in its raw state (Tr) and after activation as carbon (CAT). The materials were characterised by determining their point of zero charge (pHpzc) and by scanning electron microscopy (SEM). Adsorptive performance was analyzed using Langmuir and Freundlich isotherms and pseudo-first- and pseudo-second-order kinetic models. The results showed greater capacity and efficiency in CAT. Tr kinetics fitted the pseudo-second-order model, while CAT did not provide a conclusive fit. Activated Moringa oleífera is proposed as a sustainable and efficient adsorbent for the removal of cationic dyes in water.
