Polymeric Inclusion Membranes Based on Ionic Liquids for Selective Separation of Metal Ions.

In this work, poly(vinyl chloride)-based polymeric ionic liquid inclusion membranes were used in the selective separation of Fe(III), Zn(II), Cd(II), and Cu(II) from hydrochloride aqueous solutions. The ionic liquids under study were 1-octyl-3-methylimidazolium hexafluorophosphate, [omim][PF] and methyl trioctyl ammonium chloride, [MTOA][Cl]. For this purpose, stability studies of different IL/base polymer compositions against aqueous phases were carried out.

Science production of pesticide residues in honey research: A descriptive bibliometric study.

This work aims to provide a comprehensive study of the available research information on pesticide residues in honey through literature analysis. The research advancements within this research field from 1948 to 2019 are addressed using the Web of Science database. The results from the 685 articles analyzed indicate that this research field is in the focus of interest nowadays (Price index: 47.

A descriptive bibliometric study on bioavailability of pesticides in vegetables, food or wine research (1976-2018).

A bibliometric analysis based on the Web of Science© (WOS) database was performed on bioavailability of pesticides in vegetables, food or wine related studies published from inception to 2018. A total of 1202 articles were subjected to examination. The results reveal that yearly production of scientific articles increased steadily.

Bioreactor Membranes for Laccase Immobilization Optimized by Ionic Liquids and Cross-Linking Agents.

A novel concept of membrane bioreactor based on polymeric ionic liquids laccase membrane has been implemented in batch process for decolorization of the anthraquinonic dye Remazol Brillant Blue R (RBBR). New laccase immobilization strategy has been optimized by casting the enzyme into a polymeric inclusion membrane (PIM) using ionic liquids (ILs) and polyvinyl chloride (PVC) leading to laccase polymeric IL membrane (PILM). Four different ILs (1-octyl-3-metylimidazolium bis(trifluoromethylsulfonyl)imide, [OMIM][NTF]; cholinium bis(trifluoromethylsulfonyl)imide, [Ch ol][NTF]; cholinium dihydrogenphosphate, [Chol][HPO] and hydroxyethylammonium formate, [HEA][Fo]) have been screened and mixed to constitute the active phase of the support of PIM.

[Candida spp. in the gut microbiota of people with autism: a systematic review].

Introduction: There is great interest in studies on the implications that gut microbiota exerts on the behavior of people with autism spectrum disorders (ASD), through the microbiota-gut-brain axis. Most studies on microbiota are focused on the possible involvement of bacteria on people with ASD, but few of them are focussed on the effect of microorganisms in the Fungi kingdom.

Subjects And Methods: The present study performs a systematic review of the presence of Candida spp.

Domestic wastewaters reuse reclaimed by an improved horizontal subsurface-flow constructed wetland: A case study in the southeast of Spain.

The aim of this case study was to assess the performance of a horizontal subsurface flow constructed wetland (HF-CW) located in southeastern Spain, filled with blast furnace slags (BFS), planted with Phragmites australis and designed to treat artificially aerated domestic wastewater to produce effluents suitable for agriculture reuse. The water quality parameters, included in the Spanish regulations for reclaimed wastewater reuse as agricultural quality 2.1, were monitored for one year.

Ionic liquid technology to recover volatile organic compounds (VOCs).

Volatile organic compounds (VOCs) comprise a wide variety of carbon-based materials which are volatile at relatively low temperatures. Most of VOCs pose a hazard to both human health and the environment. For this reason, in the last years, big efforts have been made to develop efficient techniques for the recovery of VOCs produced from industry.

A whole biodiesel conversion process combining isolation, cultivation and in situ supercritical methanol transesterification of native microalgae.

A coupled process combining microalgae production with direct supercritical biodiesel conversion using a reduced number of operating steps is proposed in this work. Two newly isolated native microalgae strains, identified as Chlorella sp. and Nannochloris sp.

Discovering less toxic ionic liquids by using the Microtox® toxicity test.

New Microtox® toxicity data of 16 ionic liquids of different cationic and anionic composition were determined. The ionic liquids 1-butyl-1-methylpyrrolidinium trifluoromethanesulfonate, [BMPyr(+)][TFO(-)], 1-butyl-1-methylpyrrolidinium chloride, [BMPyr(+)][Cl(-)], hydroxypropylmethylimidazolium fluoroacetate, [HOPMIM(+)][FCH2COO(-)], and hydroxypropylmethylimidazolium glycolate [HOPMIM(+)][glycolate(-)] were found to be less toxic than conventional organic solvent such as chloroform or toluene, accoding the Microtox® toxicity assays. The toxicity of pyrrolidinium cation was lower than the imidazolium and pyridinium ones.

Organosolv extraction of lignin from hydrolyzed almond shells and application of the delta-value theory.

The solubility of lignin from hydrolyzed almond (Prunus amygdalus) shells in different acetone, ethanol and dioxane-water mixtures and conditions (extraction time and temperature) was studied. The concept of the solubility parameter (delta-value) was applied to explain the effect of organic solvent concentration on lignin solubility. The organic solvent-water mixture that led to the highest lignin extraction was composed of a 75% vol.
