Which route to take for diclofenac removal from water: Hydroxylation or direct photolysis?
(2019-09-01)
This study aimed at comparing the performance of hydroxylation and direct photolysis for removing diclofenac from water. Several parameters were assessed: degradation kinetics, mineralization degree, lipophilicity (log ...
Direct short-wave photolysis of chlorpyrifos-methyl and chlorpyrifos-methyl oxon in the presence of cyclodextrins
(Springer, 2021-04)
Direct short-wave photolysis of chlorpyrifos-methyl (1) and chlorpyrifos-methyl oxon (2) was studied in the presence of native cyclodextrins (α–, β– and γ–CD) and randomly methylated β–CD (RAMEB). We used for irradiation ...
Phototransients of 2-ethylaminodiphenylborinate generated by direct photolysis and photosensitization
(ELSEVIER SCIENCE SALAUSANNE, 2012)
Ground state interactions and excited states and transients formed after photolysis and photosensitization of 2-ethylaminodiphenylborinate (2APB) were studied by various techniques. The UV spectrum shows a large absorption ...
Analytical Methods in Photoelectrochemical Treatment of Phenol
(Soc Brasileira Quimica, 2011-09-01)
The aim of the study was to propose a treatment of simulated wastewater containing phenol by photocatalytic and photolytic processes and analyze the toxicity of these phenolic solutions. Two treatment systems were performed ...

Direct Irradiaton of Aryl Sulfides: Homolytic Fragmentation and Sensitized S-Oxidation
(American Chemical Society, 2017-09)
The direct irradiation of diphenyl sulfide and p-substituted thioanisoles in the presence of oxygen was investigated by means of both steady state and laser flash photolysis experiments. Two competitive pathways took place ...
Direct measurement of two-photon action cross section
(American Chemical Society, 2019-03-27)
We present a simple and fast methodology for measuring the two-photon (2P) action cross section of phototriggers. The method uses a standard 2P microscopy setup for both uncaging and detection and a set of lithographically ...
