En la búsqueda de mejores condiciones para remover material precursor en la formación de subproductos de desinfección con cloro libre, se encontró que la absorbancia al ultravioleta a 254 nm (AUV 254 nm) es un parámetro que puede ser usado como medida no especifica para estimar concentraciones de material precursor, específicamente sustancias húmicas, y además, como instrumento de control en las operaciones y procesos previos a la desinfección con cloro libre. El estudio plantea la importancia para que en los ensayos de tratabilidad de agua para potabilización se incluya la AUV 254 nm como parámetro de control, ya que en ensayos de coagulación con alumbre se encontró que la remoción de estas sustancias depende de la dosis de coagulante y el pH de coagulación.
