Impact from road transport of radioactive wastes in Spain
General
This work focuses in transport of high level radioactive wastes, mainly consisting of spent fuels from nuclear power utilities in Spain. To date, these wastes are being stored in the own generating facilities, or they are sent to France; but these options are not any more technically or economically...
An environmental approach for the management and protextion of heavily irrigated regions
General
In this paper the results of a preliminary study that investigates water footprint (WF) concept, as a useful tool to address water management problems in cultivated areas are presented. The two basic methodologies reported in the literature, their applicability, benefits and challenges were...
Determination of Hydrogen Peroxide in Abas abad River Water Based on Catalytice effect of TiO2 Nano Particle on Peroxy Oxalate Chemiluminescenc of Triaznyl Dye Derivative
General
This work is first report showed that supported TiO2 NPs on alumina could act catalytic activity on peroxyoxalate chemiluminescence system. In this work the catalytic effect of supported Titanium dioxide nanoparticles (TiO2 NPs) on the trichloroperoxy oxalate – hydrogen peroxide (PO-CL) reaction is...
Combustion characterization of producer gas from biomass gasification
General
In the present work, premixed flames from the combustion of producer gas have been analyzed. Two different compositions have been tested, corresponding to air and steam gasification processes (the latter leading to a better quality gas due to its higher CO and H2 concentration and its lower N2...
Spectophotometric studies on the competitive adsorption of boric acid (b(iii)) and chromate (cr(vi)) onto iron (oxy) hydroxide (fe(o)oh)
General
Various pollutants (e.g. boron and hexavalent chromium) are introduced into the aquatic environment from a variety of industrial operations causing damages to environment and affecting human health. Boron in irrigation water is of particular interest because it can have beneficial or toxic effect on...
Bioethanol production from thermochemically pre-treated olive mill solid residues using the yeast Pachysolen tannophylus
General
Olive oil mill solid residue (OMSR) is the solid waste generated during olive oil production process in three-phase olive mills. It consists of the remaining pulp of olive processing after the extraction of oil, as well as the cracked seeds of the olive fruits, containing thus mainly lignocellulose...
Sensitivity analysis of different evapotranspiration methods using a new sensitivity coefficient
General
The estimation of evapotranspiration is essential in water resources management. Among a group of methods, the Penman–Monteith has been commonly applied to calculate reference evapotranspiration as this method has been also recommended by the Food and Agriculture Organization of the U.N. (FAO)...
Rapid immobilisation of 8-hydroxyquinoline onto silica materials and its application for on-line solid-phase extraction of transition metals from environmental samples before ICP-OES monitoring
General
Chelating resins based on immobilised oxines are attractive solid-phase extraction (SPE) materials in the analysis of trace metals from environmental samples. The most common immobilisation procedure for bonding oxines to silica supports is time-consuming and incompatible with “green chemistry”...
Increase of biogas production through co-digestion of lipids and sewage sludge
General
The aim of this study was to assess the feasibility of co-digesting lipids originated from domestic wastewater along with sewage sludge. Three lab-scale single stage mesophilic anaerobic digesters were operated under a constant hydraulic retention time (15 days). One system (C) was fed on a daily...
