Pharmaceutical compound in wastewater has become an important issue as the
wastewater treatment plant did not treat them and may affect the reuse and disposal
of wastewater. Advanced Oxidation Process (AOPs) is one of the effective process
which involve heterogeneous photocatalysis by using semiconductor metal oxide and
ultraviolet as the light sources in producing clean water. This study investigated the
use of a range of different amount of UV/LED which are 30, 60 and 90 as the light
source and the interaction between TiO2 as photocatalyst which eventually cause the
degradation of pharmaceutical in wastewater. Results have shown that as confirmed
in UV-Vis analyses, degradation of paracetamol which is as the target of
pharmaceutical in wastewater is achieved with higher amount of UV/LED and less
amount of TiO2 used. Overall, it shows that UV/LED and photocatalyst plays an
important role in removal of paracetamol in wastewater.
