Abstract

The Removal efficiency of methyl orange using two kinds of magnetic photocatalysts containing ZnO in the presence and absence of Graphene oxide is investigated. Meanwhile, the kinetic of removal reaction of methyl orange, the effect of operational parameters such as irradiation time and weight fraction of photocatalysts based on statistical method and Duncan’ s multiple range test are studied. The Removal efficiency of methyl orange using both of the applied photocatalysts is affected by irradiation time and weight fraction of photocatalyst. So that the enhancement of these two parameters leads to the increment of Removal efficiency of methyl orange. The results show that the kinetic reaction is pseudo first order. The rate of reaction using photocatalyst containing graphen oxide is higher than that of without it. The results of statistical analysis based on Duncan’ s multiple range test reveals that both of the studied parameters have significant influence on the Removal efficiency of methyl orange.
