| Abstract |
The photodegradation of ibuprofen (IBP) in aqueous media was studied in this paper. The degradation mechanism, the reaction kinetics and toxicity of the photolysis products of IBP under UV-Vis irradiation were investigated by dissolved oxygen experiments, quenching experiments of reactive oxygen species (ROS), and toxicity evaluation utilizing Vibrio fischeri. The results demonstrated that the IBP degradation process could be fitted by the pseudo first-order kinetics model. The degradation of IBP by UV-Vis irradiation included direct photolysis and self-sensitization via ROS. The presence of dissolved oxygen inhibited the photodegradation of IBP, which indicated that direct photolysis was more rapid than the self-sensitization. The contribution rates of ·OH and (1)O2 were 21.8 % and 38.6 % in self-sensitization, respectively. Ibuprofen generated a number of intermediate products that were more toxic than the base compound during photodegradation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 March 2015.
All research outputs
#21,608,038
of 24,119,703 outputs
Outputs from Bulletin of Environmental Contamination and Toxicology
#3,090
of 4,112 outputs
Outputs of similar age
#313,745
of 367,500 outputs
Outputs of similar age from Bulletin of Environmental Contamination and Toxicology
#40
of 77 outputs
Altmetric has tracked 24,119,703 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,112 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 367,500 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 77 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
