Photocatalyst is known as a substance activated by adsorbing a photon and efficient
in accelerating the reaction without being consumed. The usage of paracetamol has
been increasing over years and this compound can be removed by wastewater
treatment but it is not efficient. Thus, photocatalytic degradation using titanium
dioxide (TiO2) as a catalyst can eliminate the paracetamol contained in water source.
This study is done by varying the concentration of titanium dioxide using UV LED and
Black light as an illumination source and to compare the efficiency of these two
illumination source as to investigate the key parameters: catalyst load. The result
obtained showed that UV LED is more efficient in photocatalytic degradation compared
to black light and for the catalyst load, as the concentration of catalyst increases, the
performance of degradation decreases. Paracetamol can be a harm to everyone, thus
photocatalytic degradation can eliminate paracetamol in our drinking sources.
