Rapid characterisation of agro-industrial effluents for environmental fate by UV–visible and infrared spectroscopy from fractions obtained by centrifugation
(Taylor & Francis Ltd, 2017-06)
Agro-industrial systems (e.g. dairy farms, feed lot, pig breeding and food processing plants) provide large quantity of organic wastes that could be recycled within the productive systems. However, the basic chemical ...
Pd and Pd,In nanoparticles supported on polymer fibres as catalysts for the nitrate and nitrite reduction in aqueous media
(Elsevier Ltd, 2019-12)
The presence of high concentrations of nitrate and nitrite ions in water sources is an actual environmental problem. Nowadays, there are several technologies for nitrate and nitrite treatment, but most of them involve the ...
Magnetic monitoring of anthropogenic pollution in Antarctic soils (Marambio Station) and the spatial-temporal changes over a decade
(Elsevier Science, 2021-08)
Marambio Station is one of the most important human settling in the Antarctic Peninsula, which has been polluted by human activities since the 1970s. Following the first magnetic monitoring in Antarctic soils (austral ...
Infrared assisted digestion used as a simple green sample preparation method for nutrient analysis of animal feed by microwave induced plasma atomic emission spectrometry
(Elsevier Science, 2021-08)
Based on green analytical chemistry principles it is important to evolve procedures that convert solid samples into solutions without using excessive reagent quantities, energy, temperature, and avoiding waste generation. ...
Microwave-assisted conditions for the green synthesis of thioacetamide. Optimization of reaction parameters using response surface methodology
(Elsevier B.V., 2018-09)
An optimized method for the synthesis of thioacetamide (TA) in relation to the consumption of materials and energy, which reduces the production of waste and minimizes costs, is hitherto presented. The most important ...
Metal biorecovery and bioremediation: Whether or not thermophilic are better than mesophilic microorganisms
(Elsevier, 2019-05)
Metal mobilization and immobilization catalyzed by microbial action are key processes in environmental biotechnology. Metal mobilization from ores, mining wastes, or solid residues can be used for recovering metals and/or ...
Short-term dynamics of soil chemical parameters after application of alperujo in high-density drip-irrigated olive groves in Argentina
(Taylor & Francis, 2012-08)
Two-phase olive oil mills generate a semi-solid waste made of olive pulp, olive stone, and vegetation water commonly called ‘alperujo’. Lack of disposal alternatives drives many Argentinean olive oil producers to apply it ...
Enzymatic unhairing: Permeability assay of bovine skin epidermis with fungal enzyme extracts
(Asociación Química Española de la Industria del Cuero, 2019-07)
The aim of enzymatic unhairing is to allow the separation of the outer sheath of hair root from the dermal connective tissue. This is considered an ecofriendly process. It?s not expensive since if the enzymes are applied ...
Valorization of corn cob for the obtention and purification of endoglucanase produced by SSF
(Elsevier, 2020-01)
Agro-food by-products contain valuable nutrients which are wasted. In this work, solid-state fermentation (SSF) was carried out using corn cob as substrate for endoglucanase production. The radial growth of three fungal ...
Estudio de la actividad antifúngica de materiales conteniendo carbón proveniente de pilas en desusoStudy of the antifungal activity of materials containing coal from disused batteries
(Universidade Federal do Rio de Janeiro, 2018-03-19)
La gran cantidad de pilas que se descartan y el impacto ambiental que la inadecuada disposición de los residuos de las mismas produce impulsó a su reciclado. Tanto las pilas alcalinas como las de cinc-carbón tienen como ...
