Removing Phosphate From Aquatic Environments Utilizing Fe-Co/Chitosan Modified Nanoparticles

Resumen

Se utilizaron nanopartículas de hierro-cobalto modificado con quitosano (CMNP) para la adsorción de fosfato en aguas residuales sintéticas y aguas del río Jordán en Tunja, Boyacá, Colombia. La adsorción de fosfato por los CMNP alcanzó el 52,7% en aguas residuales sintéticas y el 58,7% en agua extraída del río Jordán. Esto indica que la capacidad de CMNP para adsorber fosfatos es independiente de otros componentes dentro del agua del río. Además, las medidas de adsorción se tomaron utilizando el pH, la temperatura y la concentración de fosfato promedio del agua del río para garantizar resultados comparables a los de (Kim 2017). Se encontró una tasa de adsorción máxima de 0.138 mg de fosfato por gramo de adsorbente y la mayoría de la adsorción tuvo lugar dentro de los primeros 15 minutos de contacto con el adsorbente. La adsorción de fosfatos usando CMNPs presenta una solución efectiva y ecológica para reducir los fosfatos en los ecosistemas acuáticos sin alterar las características del agua del río.
