Kinetic study of the photo-Fenton degradation of formic acid: Combined effects of temperature and iron concentration
(Elsevier, 2009-02)
This study is focused on the kinetic modelling of the Fenton and photo-Fenton degradation of a model pollutant (formic acid) in aqueous solution, for relatively low iron concentrations (1–9 ppm). The reaction rate expressions ...
Surface diffusion of poisoning species during CO and formic acid oxidation on PtAu surface. The key role of the active site
(Elsevier Science, 2021-01-31)
A comparative study of the Pt and Pt/Au surface towards CO and formic acid oxidation was performed by conventional electrochemical techniques used in combination with an electrochemical flow cell (four-electrode configuration) ...
ÁCIDO FÓRMICO EN GEL PARA REGULAR SU EVAPORACIÓN

Accuracy, precision and robustness of different methods to obtain samples from silages in fermentation studies
(Sociedade Brasileira de Zootecnia, 2012)
The objective of this study was to evaluate accuracy, precision and robustness of two methods to obtain silage samples, in comparison with extraction of liquor by manual screw-press. Wet brewery residue alone or combined ...
Electrocatalytic activity under oscillatory regime: The electro-oxidation of formic acid on ordered Pt3Sn intermetallic phase
(2013-01-05)
Despite the considerable progress in the understanding of the mechanistic aspects of the oscillatory electro-oxidation of C1 molecules, there are apparently no systematic studies concerning the impact of surface modifiers ...

Evaluation of Trace Elements in Marine Biological Tissues by Graphite Furnace Atomic Absorption Spectrometry After Sample Treatment with Formic Acid
(2022-01-01)
In this work, formic acid was used as an extracting solvent in a fast and accurate procedure for Cd and Pb determination in biological tissue by graphite furnace atomic absorption spectrometry (GF AAS). The procedure ...
Reduction of nitrate by heterogeneous photocatalysis over pure and radiolytically modified TiO2 samples in the presence of formic acid
(Elsevier Science, 2017-03)
Heterogeneous photocatalytic reduction of nitrate (2 mM) in the presence of formic acid (FA, 10 mM) using pure and modified TiO2 samples under UV–vis irradiation was performed at pH 3, and the evolution of the intermediate ...
Influence of ethylene glycol, ethanol and formic acid on platinum and ruthenium electrodeposition on carbon support material
(Springer, 2009-07)
Carbon supported Pt-Ru catalysts were prepared by potentiostatic deposition at -0.5 V from H2PtCl6 + RuCl3 in H 2SO4 solution in the presence of ethylene glycol (EG), ethanol (EtOH) and formic acid (HCOOH) as stabilizing ...
Catalytic enhancement of formic acid electro-oxidation through surface modifications with gold on supported Pt nanoparticles
(Pergamon-Elsevier Science Ltd, 2019-01)
The Formic Acid Electro-oxidation (FAEO) on Pt/Au Nanoparticles (PtAu NP) supported on Hierarchical Porous Carbon (HPC), was studied by cyclic voltammetry and chronoamperometry. The supported HPC-Pt nanoparticles were ...
