UV-C radiation based methods for aqueous metoprolol elimination

Synthesis and characterization of B-doped TiO2 and their performance for the degradation of metoprolol

“…This low value explains the MET stability when exposed to this type of irradiation. Rivas et al [26] also observed that MET phototransformation process is not fast enough and the low value of molar absorption coefficient of MET confirms the previous experimental facts.…”

“…The advanced oxidation processes (AOPs) have been highlighted, with satisfactory results in the removal of several organic compounds including pharmaceuticals [10,[18][19][20][21][22][23]. Studies have reported the removal of MET by different AOPs, including ozonation [12], UV/H 2 O 2 [24], photo-Fenton [25][26][27], photocatalysis [12,14,[28][29][30][31].…”

Photocatalytic degradation of metoprolol tartrate in suspensions of two TiO2-based photocatalysts with different surface area. Identification of intermediates and proposal of degradation pathways

“…It blocks the action of epinephrine and norepinephrine on the β-adrenergic receptors in the body, primarily in the heart [13]. MET is characterized by an increasing use in recent years and, as a consequence, its occurrence in aqueous effluents is expected to increase as well [14,15]. MET shows slow direct phototransformation and/or hydrolysis [16,17].…”

Photocatalysis of β-blockers – An overview

“…In recent years, the presence of b-blockers in environmental matrices has received a special attention by the scientific community due to increasing use and limited human metabolism (Alder et al, 2010;Huggett et al, 2003;Rivas et al, 2010). After being used, they are released into sewage waste water treatment system and surface waters as metabolites as well as unchanged parent molecules.…”

“…Mineralization was negligible in the photolysis compared with the photocatalysis because there are no other photosensitive compounds in water to generate hydroxyl radicals which are main reactive species for propranolol removal. Rivas et al (2010) investigated the efficiency of several UV-C radiation based methods for the mineralization of metoprolol. Mineralization was performed by means of UV-C, UV-C/H 2 O 2 , UV-C/percarbonate, UV-C/monopersulphate, UV-C/TiO 2 , UV-C/H 2 O 2 /TiO 2 and photo-Fenton (Fe 2+ and H 2 O 2 ) reagent.…”
