Propranolol hydrochloride degradation using La@TiO2 functionalized with CMCD
文献摘要：
Propranolol hydrochloride can be considered a persistent and bioaccumulative pharmaceutical in the environment.This drug and its by-products are potentially toxic and have adverse effects,since these compounds have been associated with endocrine-disrupting effects,reproductive deficiencies,embryo abnormalities and pericardial oedema.TiO2-La 0.05％-carboxymethyl-β-cyclodextrin(CMCD)nano-particles were successfully prepared by a simple two-step method,which consists of sonification and functionalization.The characterization analyses reveal that lanthanum is dispersed on the semi-conductor surface,probably forming Ti-O-La bonds,which can induce oxygen vacancies and surface defects that effectively restrain the recombination of photogenerated electron/holes pairs.The efficiency of TiO2-La 0.05％-CMCD samples in degradation of propranolol under UV-light irradiation is higher than that of pristine TiO2 within 20 min reaction,probably due to complex formation between the β-blocker and the oligosaccharide,which allows us to propose a photocatalytic mechanism based on the formation of intermediates and competition of these compounds to the radicals and CMCD cavities.
