Acetaminophen is a drug belonging to the group of non-steroidal antiinflammatories,
it is one of the most widely used drugs, its overdose causes toxic
effects such as hypoglycaemia and liver failure. It is one of the pharmaceutical
compounds commonly found in the various reports on wastewater and natural
waters, it has been located in different countries such as the United States,
Canada, Germany, South Korea, among others, showing its continuous presence
in the environment and its resistance to degradation. In this work, a kinetic study
is carried out on the degradation of acetaminophen, modifying the
concentration of the photocatalyst and the drug. For the above, a solar simulator
Suntest CPS + and photocatalytic materials based on bismuth oxide (Bi2O3)
were used because these materials have presented a very good photocatalytic
activity attributed mainly to their wide band gap (2-3.9 eV), These materials were
doped with gadolinium (Gd 3+ ) in 0.5 and 1% w/w to further improve their
photoactivity, and characterizations were made to observe the effects produced
by the dopant. The best photoactivity was obtained with the material 0.5% w /
w (100%, t = 180 min); however, when it use the sample with 1% w/w of dopant
Gd 3+ the mineralization is better (98%) despite its degradation is lower
