Application of a stable Ag/TiO2 film in the simultaneous photodegradation of hormones
(2020-10-01)
BACKGROUND: The natural hormones estrone (E1) and 17β-estradiol (E2) and the synthetic hormone 17α-ethynylestradiol (EE2) are excreted daily by humans and may reach water and wastewater treatment plants, which do not ...
Treatment of ethylmercury chloride by heterogeneous photocatalysis with TiO2
(Elsevier Science SA, 2021-04)
Ethylmercury chloride (C2H5HgCl) was treated by UV/TiO2 photocatalysis in the presence of O2 and under N2 at pH 4.2. No report exists on C2H5Hg+ degradation by heterogeneous photocatalysis. The adsorption of C2H5Hg+ over ...
Deposition of TiO2 thin films by dip-coating technique from a two-phase solution method and application to photocatalysis
(2021-01-01)
A derivation of the sol-gel-dip-coating deposition technique is proposed, where the precursor solution exhibits two separated liquid phases, reaching an equilibrium state in a heterogeneous solution. Structural, optical ...
Degradation of [D-Leu]-Microcystin-LR by solar heterogeneous photocatalysis (TiO2)
(Pergamon-Elsevier B.V. Ltd, 2012-09-01)
The present study investigates the use of solar heterogeneous photocatalyis (TiO2) for the destruction of [D-Leu]-Microcystin-LR, powerful toxin of widespread occurrence within cyanobacteria blooms. We extracted ...

Phenylmercury degradation by heterogeneous photocatalysis assisted by UV-A light
(2013)
Photocatalytic degradation of phenylmercury was studied using TiO2 in aqueous suspension assisted by UV-A irradiation. Reaction conditions, such as pH and amount of TiO2 were set using a factorial design of experiments ...
Heterogeneous photocatalytic degradation of acid dyes in aqueous TiO2 suspensions: Kinetics and toxicity
(SCIENCE & TECHNOLOGY NETWORK INC, 2008)
This work assesses the photocatalytic (TiO2/UV) degradation of a simulated acid dye bath (Yellow 3, Red 51, Blue 74, and auxiliary chemicals). Color and phytotoxicity removal were monitored by spectrophotometry and lettuce ...
