Comparison of the Simple Cyclic Voltammetry (CV) and DPPH Assays for the Determination of Antioxidant Capacity of Active Principles
Fernández Arteaga, Jesús
; Ruiz Montoya, Mercedes; Palma López, Alberto; Alonso Garrido, Gema; Pintado, Sara; Rodríguez Mellado, José Miguel (MDPI, 2012)
Antioxidant activity of a number of small (low molecular weight) natural compounds found in spices, condiments or drugs (gallic acid, sesamol, eugenol, thymol, carvacrol, vanillin, salicylaldehyde, limonene, geraniol, ... -
Desarrollo e implementación de métodos electroquímicos para determinar la capacidad antioxidante de muestras orgánicas
Palma López, Alberto (Universidad de Huelva, 2015)
El estrés oxidativo es uno de los procesos bioquímicos estudiados de mayor relevancia en los últimos años que surge como consecuencia de un desequilibrio entre las sustancias antioxldantes y prooxidantes. Este fenómeno ... -
Determination of antioxidant activity of spices and their active principles by Differential Pulse Voltammetry
Palma López, Alberto; Ruiz Montoya, Mercedes; Fernández Arteaga, Jesús; Rodríguez Mellado, José Miguel (American Chemical Society, 2014)
The anodic oxidation of mercury in the presence of hydrogen peroxide in differential pulse voltammetry (DPV) was used to determine the antioxidant (AO) character of radical scavengers. Hydroperoxide radical is formed at ... -
Electrochemical Determination of Glyphosate in Waters Using Electrogenerated Copper Ions
Pintado, Sara; Ruiz Montoya, Mercedes; Rodríguez Amaro, Rafael; Mayén, Manuel; Rodríguez Mellado, José Miguel (ESG, 2012)
Carbon electrodes with in situ electrodeposited copper are used to the determination of Glyphosate (N-(phosphonomethyl) glycine) in drinking waters. The oxidation signal to form Cu(II) ions is enhanced after the addition ... -
Influence of Cellulose Characteristics on Pyrolysis Suitability
Eugenio, María Eugenia; Ruiz Montoya, Mercedes; Martín Sampedro, Raquel; Ibarra, David; Díaz Blanco, Manuel Jesús (MDPI, 2021)
: Cellulose is the most abundant component of biomass and the one that requires the most activation energy (Ea) for pyrolysis. In this study, the dependence of Ea on the intrinsic cellulose characteristics, such as the ... -
Influencia de las variables de operación en la composición de los Compuestos Orgánicos Volátiles generadores de olor emitidos en el compostaje de RSU
Delgado Rodríguez, Margarita; Cabeza, I. O.; Ruiz Montoya, Mercedes; Giráldez Díaz, Inmaculada; López, Rafael; Madejón Rodríguez, Engracia; Díaz Blanco, Manuel Jesús (Olores.org, 2012)
En el presente estudio se ha evaluado la influencia de los parámetros de control utilizados en el compostaje de Residuos Sólidos Urbanos (RSU), como son la aireación (0.05-0.300 Laire kg-1 min-1) y la humedad (40-70%) en ... -
Kinetic synergistic effect in co-pyrolysis of Eucalyptus globulus with high and low density polyethylene
Ruiz Montoya, Mercedes; Palma López, Alberto; Lozano Calvo, Susana; Morales Carrillo de Albornoz, Emilio; Díaz Blanco, Manuel Jesús (Elsevier, 2022-08-13)
The pyrolysis of Eucalyptus globulus (EG) with different blends of high density polyethylene (HDPE) and low density polyethylene (LDPE) by thermogravimetry has been studied. ASTM-E1641-16 standard method has been used to ... -
MSW Compost Valorization by Pyrolysis: Influence of Composting Process Parameters
Palma López, Alberto; Doña Grimaldi, Victor; Ruiz Montoya, Mercedes; Giráldez Díaz, Inmaculada (American Chemical Society, 2020-08)
The valorization of urban solid waste compost (MSW) in two different composting conditions (different aeration and humidity) has been studied (we work with the hypothesis that the composting process can have a significant ... -
Optimización de las variables implicadas en el proceso de compostaje de RSU para minimizar la emisión de compuestos orgánicos volátiles
Delgado Rodríguez, Margarita (Universidad de Huelva, 2012)
La generación de olores emitidos por las plantas de compostaje supone un gran impacto ambientan proveniente del manejo de Residuos Sólidos Urbanos (RSU). Parámetros como composición de residuos, tecnología de compostaje, ... -
Pyrolysis kinetic, thermodynamic and product analysis of different leguminous biomasses by Kissinger-Akahira-Sunose and pyrolysis-gas chromatography-mass spectrometry
Clemente Castro, Sergio; Palma López, Alberto; Ruiz Montoya, Mercedes; Giráldez Díaz, Inmaculada; Díaz Blanco, Manuel Jesús (Elsevier, 2022)
To ascertain the potential of various leguminous biomass such as L. leucocephala, C. proliferus, P. alba and S. sesban, both energetic and a source of high added value products, the pyrolytic behaviour was studied at ... -
Thermogravimetry Applicability in Compost and Composting Research: A Review
Díaz Blanco, Manuel Jesús; Ruiz Montoya, Mercedes; Palma López, Alberto; Paz Bañez, María Violante de (MDPI, 2021-02)
Composting could be a suitable solution to the correct treatment and hygienization of several organic waste, producing compost that can be used in agriculture. The evolution and maturity of this process has been studied ... -
Ultrasound extraction optimization for bioactive molecules from Eucalyptus globulus leaves through antioxidant activity
Palma López, Alberto; Díaz Blanco, Manuel Jesús; Ruiz Montoya, Mercedes; Morales Carrillo de Albornoz, Emilio; Giráldez Díaz, Inmaculada (Elsevier, 2021)
Antioxidant products present a very high added value and are demanded in the market. The optimization of their extraction is a high-stakes matter for both economic and environmental points of view. Ultrasound extraction ... -
Uso de una Nariz electrónica para el estudio de la biofiltración de α-pineno con composts de residuos sólidos urbanos y restos de poda
López, Rafael; Cabeza, I.; Lock-Wah-Hoon, J. R.; Giráldez Díaz, Inmaculada; Ruiz Montoya, Mercedes; Díaz Blanco, Manuel Jesús (Olores.org, 2012)
Las plantas de compostaje causan frecuentemente problemas de malos olores por los compuestos orgánicos volátiles (COV) emitidos, entre ellos el pineno. En el presente trabajo se estudia la eficacia de dos biofiltros rellenos ...
