Oxidación catalítica heterogénea de azul de metileno

Abstract

En el presente trabajo se estudió ladegradación de azul de metileno (AM) utilizando como oxidante peróxido dehidrogeno, catalizado por oxido de niobio V. Se investigó el efecto del pH,transferencia de masa, tratamiento previo y reúso del catalizador, concentraciónde contaminante y lixiviación de Nb. Se buscaron las concentraciones optimas dereactivo y catalizador, siendo estas de 1.5% y 0.05% m/m, respectivamente.El catalizador y reactivo aplicadosen condiciones óptimas produjeron un alto porcentaje de degradación del AM entodos los ensayos realizados, mostrando la alta reactividad del procesopropuesto. Se observó que los procesos de tratamiento previo y reúso delcatalizador aumentan la reactividad del catalizador siendo un resultadoimportante para su aplicación.
