Parameters affecting LED photoreactor efficiency in a heterogeneous photo-Fenton process using iron mining residue as catalyst
(Taylor & Francis Inc, 2019-07-17)
In this article, a light-emitting diode (LED)-based photoreactor was designed and evaluated for degradation of the antibiotic sulfathiazole (STZ), using heterogeneous photo-Fenton process with an iron ore residue as catalyst. ...
Design and Analysis of Homogeneous and Heterogeneous Photochemical Reactors
(Wiley, 2005)
A short chapter to make a complete discussion of photoreactoreactor analysis and design is an impossible task unless we decide that the readers of this work have a previous background on the subject and chemical engineering ...
