Durante o processo metalúrgico de usinagem de uma peça ocorre a geração de calor proveniente do atrito ferramenta/peça e cavaco/ferramenta. Para que ocorra uma menor geração de calor possibilitando o manuseio, bem como a minimização na deformação da peça, utilizam-se fluidos, que são soluções lubrificantes à base de óleos, água ou polímeros, podendo ser sintéticos ou não, diminuindo, assim, o coeficiente de atrito reduzindo-se a quantidade de calor gerado no processo.

The present study is aimed to analyse the degradation of caffeine in water employing an advanced oxidation process, the photo-Fenton reaction (H2O2/Fe2+/UV). Different concentrations of H2O2 and Fe2+ are used to evaluate the effects of the two reagents on the quality of the water after the reaction and on the kinetics of degradation. The quality of the water is estimated in terms of conductivity, turbidity, colour and aromaticity. These quantities were found to be not dependent on H2O2 concentrations, whereas the Fe2+ concentration affects them in a proportional way. Compared to the limits of

Among various AOPs, Fenton’s reagent has been known to be an effective and simple oxidant. It is found that the Fenton reaction can be an efficiency enhanced in photo-electro-Fenton process since ferric may complex with certain target compounds or byproducts, especially those acting as ligands, produced by UVA light and current. The new design of our system came from the concept of promoting the ferric reduction rate, w

The decomposition by traditional acid process or physical oxidation and biological disposal are undesirable. This incomplete treatment of the wastewater will impact environment.

The used oxidants were H2O2 and Na2S2O8; additionally, the metal ions were Fe2+ and Fe3+. The effects of oxidant concentration, metal ion dosage, wavelength of UV light, US irradiation and the addition of radical scavenger were determined in this work. The experimental data indicated that the concentration of oxidant had a threshold limit for the decolorization of RR2. However, the decolorization rate of RR2

Since carbofuran exhibits a special biorefractory character and require longer biodegradation time, its complete degradation in a shorter time could only be achieved by advanced oxidation processes. Therefore, photochemical oxidation i.e. photo-Fenton process has been considered as a promising technology for the degradation of carbofuran.

The possible inductive Fe(III) reduction i.e. Fe(II) regeneration mechanisms may include direct photoreduction, photodecarboxylation, photosensitization, and quinone-like cycle reduction.
