Síntesis, caracterización y capacidad adsortiva de las nanopartículas de magnetita para la eliminación de metales en aguas superficiales
Palabras clave:
Nanoparticulas, adsorcion, plomo, manganeso, cobre
Resumen
Se emplearon nanopartículas de magnetita (NPm) que actuaron como eficientes adsorbentes para la eliminación de metales como plomo (Pb), cobre (Cu) y manganeso (Mn) en aguas superficiales. Las NPm fueron sintetizadas por el método de coprecipitación y caracterizadas por técnicas como RAMAN, TEM, BET y FTIR. Los resultados experimentales arrogaron picos de 480, 560, 600 y 654 cm-1 característicos de la magnetita con la espectroscopia RAMAN, con un tamaño promedio de nanopartícula de 10 nm mediante la técnica de TEM y con un área de superficie de 129.72 mg2g-1 en BET. Los parámetros óptimos de adsorción de los metales se llevaron a cabo en batch con 5 mg de NPm como adsorbente. Las eficiencias de remoción mostraron que la eficiencia máxima se logró para el metal Pb de 95.67 %, y un porcentaje mínimo para Mn 53.89% y 50.73% Cu debido a una atracción electrostática diferente entre los metales pesados. Se determinó que el modelo de pseudo segundo orden presento un mejor ajuste para la cinética de reacción de los tres metales. Los resultados obtenidos demuestran el alto rendimiento de las NPm para remover metales en aguas superficiales.
