Abdul Fataf, Nur Solehah (2017) The effect of Ti02 on azo dye (tartrazine) degradation process using uv light / Nur Solehah Abdul Fataf. [Student Project] (Unpublished)


The effect of contaminants to human health and environment are at alarming rate.
This is because, wastewater are polluted with the effluent coming from industry
especially food industry. Food industries use various types of dyes such as azo
dyes, anthraquinone and triphenylmethane. In this study, the dye used was azo
dye which is Trartrazine. Plus, there are many research shows that Tartrazine can
cause harm and suffers to the environment especially human health. Ergo,
researchers found so many ways to treat azo dye in wastewater effluent such as
photocatalytic degradation process. Photocatalytic degradation by using Ti02 as
the catalyst is proven efficient to degrade the dye. This study was conducted to
determine the optimum weight of Ti02, pH, r:adiation time and to evaluate the
effectiveness of Ti02 as photocatalyst in the photodegradation process by using
UV radiation under different parameters. The parameters are in the absence of
catalyst and UV radiation, absence of catalyst in the presence of UV radiation,
presence of catalyst in the absence of UV radiation and in the presence of catalyst
and UV radiation. Based on this research, optimum conditions that can increase
the percent of degradation were 30 mg of catalyst in pH 7. For optimum time,
different conditions have different optimum time. Nevertheless, among four
conditions that have been set, the results show that photodegradation in the
presence of catalyst and UV radiation has the highest percent of degradation
which 90.3%. This indicates that this condition was the most effective condition
for photodegradation to occur.
