Sonophotocatalytic Degradation of Paracetamol in the Presence of Iron-doped Titanium Dioxide

In recent years, growing consideration has been given to the presence of emerging pollutants (EPs) in water sources. EPs such as paracetamol possess characteristics of bioaccumulative, persistent and highly soluble in water. However, conventional treatment methods such as physical adsorption, chlori...
