Dosages equal to or higher than 200mg.L added in time t=0 allowed Cr VI concentrations lower than 0.5 mg.L to be obtained Figure 1, indicating that most of the Cr VI became reduced to Cr III.
Dosis iguales y mayores de 200 mg.L, adicionadas en el tiempo t = 0 permitieron alcanzar concentraciones de Cr VI inferiores a 0,5 mg.LFigura 1, indicando que la mayor parte del Cr VI presente se redujo a Cr III.
