The Waste Hierarchy at the Business Level: An InternationalOutlook
Guzmán, Beatriz; Monteiro, Sónia; David, Fátima; Rodríguez, FranciscoSustainable waste management is becoming a common goal in most countries. The national legal framework largely determines the waste management practices, the socio-demographic characteristics, and the economic level of the country and, in the case of businesses, the type of business, the industry in which it operates, and the sector-specific regulations to which it is subject. This paper aims to examine the imp...
Enhancing the detection of Dinophysis spp. using electrochemical genosensors
Pereira, Eduarda; Silva, Aurora; Morais, Stephanie L.; Costa-Rama, Estefanía; Moreira, Patrícia R.; Fraga-Corral, M.; Torrado, Ana M.Background: Harmful algal blooms (HABs) pose a significant threat to the environment and public health. These blooms are defined by an accumulation of microscopic algae in water, and they can occur in lakes, rivers, estuaries, or coastal areas. Factors like the unregulated runoff of agricultural and industrial wastes into the aquatic environment [1] are believed to have transformed these ecosystems into favorab...
Is it possible to prevent Harmful Algal Blooms? An electrochemical genosensor t...
Pereira, Eduarda; Silva, Aurora; Morais, Stephanie L.; Costa-Rama, Estefanía; Moreira, Patrícia R.; Fraga-Corral, M.; Torrado, Ana M.Harmful Algal Blooms (HABs) are a very common phenomenon in the last few years that results from the accumulation of microalgae, such as dinoflagellates of the Dinophysis genus. Hence, the development of analytical technologies capable of detecting these microorganisms and thereby avoiding environmental and public health crisis, has become a major priority. Biosensors have been gaining recognition lately given ...

Separation of benzene from methylcycloalkanes by extractive distillation with c...
Ayuso, Miguel; Navarro, Pablo; Palma, André M.; Larriba, Marcos; Delgado-Mellado, Noemí; García, Julián; Rodríguez, Francisco; Coutinho, João A. P.The aromatic/aliphatic separation using ionic liquids (ILs) has been proposed as an enhanced technology when compared to conventional liquid-liquid extraction and extractive distillation processes. Some ILs show extractive properties (distribution ratios and selectivities) greater than those of conventional solvents, like sulfolane and N- methylpyrrolidone, positioning these solvents to address challenging sepa...
Imidazolium and pyridinium-based ionic liquids for the cyclohexane/cyclohexene ...
Delgado-Mellado, Noemí; Ovejero-Perez, Antonio; Navarro, Pablo; Larriba, Marcos; Ayuso, Miguel; García, Julián; Rodríguez, FranciscoThe separation of olefins/paraffins is a challenge for the petrochemical industry due to the close boiling points of these hydrocarbons. In this work we have studied the feasibility of different imidazolium and pyridinium-based ionic liquids (ILs) as alternative solvents in the cyclohexane/cyclohexene separation. Five ILs have been studied, namely 1-butyl-4-methylpyridinium tricyanomethanide ([4bmpy][TCM]), bis...
Experimental screening towards developing ionic liquid-based extractive distill...
Navarro, Pablo; Larriba, Marcos; Delgado-Mellado, Noemí; Ayuso, Miguel; Romero, Marta; García, Julián; Rodríguez, FranciscoIonic liquids (ILs) are potential neoteric solvents to design new advanced separation processes. Among several separation cases studied so far, the good performance of ILs regarding the dearomatization of liquid fuels, i.e. pyrolysis and reformer gasolines, has received especially attention. Indeed, a wide number of works has been done to characterize the phase equilibria for {aliphatic + aromatic + ILs} system...
Thermal stability of choline chloride deep eutectic solvents by TGA/FTIR-ATR an...
Delgado-Mellado, Noemí; Larriba, Marcos; Navarro, Pablo; Rigual, Victoria; Ayuso, Miguel; García, Julián; Rodríguez, FranciscoDeep eutectic solvents (DESs) based on the cation choline have been proposed to date for a variety of applications due to their remarkable physicochemical properties. The thermal stability is one of the first properties of DESs that needs to be known since it limits the maximum operating temperature for which these solvents are useful in many applications. In this work, the thermal stability of eight different ...
