| Descripción : | The objective of this work is to study, for the first time, the photodegradation of 4-chlorophenol (4CP) catalyzed by a calcined Mg Zn Al layered double hydroxides (MgAlZn LDHs) in a co-current downflow bubble column (CDBC) photoreactor at pilot scale. The effect of initial organic compound concentration, temperature, and mass catalyst over reaction rate was elucidated.
An intrinsic kinetic regime was established, and a single-site Langmuir Hinshelwood mechanism was determined to occur during
the organic compound oxidation. The catalyst was characterized by X-ray diffraction (XRD), inductively coupled plasma atomic
emission spectrometry (ICP-AES), and ultraviolet visible light (UV/vis) spectrophotometry. The reaction progress was verified by UV/vis spectrophotometry and total organic carbon (TOC) content. Degradation and mineralization rate were found to be dependent on temperature and 4CP concentration. In the range of studied operating conditions, a maximum of 94% 4CP was degraded, while 70% total organic carbon removal was achieved.
