blue (MB) under ultraviolet light irradiation. The photocatalyst used
for methylene blue degradation was the composite of titanium
dioxide and graphene, synthesized using the wet-impregnation
method. The composition of TiO2/graphene was varied into three
different mass ratios to characterize the composite further and
identify the best photocatalyst for optimization. For each mass ratio,
three affecting parameters, which were photocatalyst dosage, initial
MB concentration and irradiation time, were employed to investigate
the effects of degradation efficiency. Then, the statistical analysis for
the photocatalytic degradation of MB using the most efficient
TiO2/graphene photocatalyst was performed by utilizing the
Response Surface Methodology
