Interfaces Against Pollution

ENv14n5_FOForeword to the Special Issue from the Interfaces Against Pollution 2016 Conference: Environmental Challenges and Opportunities

Jaume Puy, Josep Galceran and Carlos Rey-Castro
pp. i-ii

EN16192Doped Ti-pillared clays as effective adsorbents – Application to methylene blue and trimethoprim removal

Beatriz González, Raquel Trujillano, Miguel A. Vicente, Vicente Rives, Emerson H. de Faria, Katia J. Ciuffi, Sophia A. Korili and Antonio Gil
pp. 267-278

Environmental context. Water is an essential compound for life; however, several factors limit the amount available for human consumption. Every day, thousands of pollutants are discharged into drinking water. Here, new materials that are efficient as adsorbents and photocatalysts for pollutants are reported.

EN16210Geometrical properties of materials for energy production by salinity exchange

A. V. Delgado, S. Ahualli, M. M. Fernández, M. A. González, G. R. Iglesias, J. F. Vivo-Vilches and M. L. Jiménez
pp. 279-287

Environmental context. Oceans and seas have the potential to play a significant role in providing renewable and clean energy. In particular, salinity difference energy aims to extract the enormous amount of energy that is released when fresh water rivers flow into the oceans. Capmix methods are focused on this challenge by using capacitive carbon electrodes whose optimisation will certainly help in developing salinity difference energy.

EN17004Desorption rate of glyphosate from goethite as affected by different entering ligands: hints on the desorption mechanism

Jeison M. Arroyave, Carolina C. Waiman, Graciela P. Zanini, Wenfeng Tan and Marcelo J. Avena
pp. 288-294

Environmental context. Glyphosate is a heavily used herbicide that is mobilised in soil and sediments through adsorption–desorption processes from the surface of mineral particles. We demonstrate that the desorption rate of glyphosate from goethite, a ubiquitous mineral, is nearly independent of the concentration and nature of the substance that is used to desorb it. The results elucidate the desorption mechanism and are relevant to understand and predict the environmental mobility of glyphosate.

EN16216The relationship between inner surface potential and electrokinetic potential from an experimental and theoretical point of view

Tajana Preočanin, Danijel Namjesnik, Matthew A. Brown and Johannes Lützenkirchen
pp. 295-309

Environmental context. Interfacial properties of colloid and nanoparticles are directly related to the reactivity and surface densities of existing surface sites. Surface characterisation of particles provides only some kind of average surface properties. Analysis of well-defined monocrystal surfaces, which form the surface of the single particle, leads to a better understanding of surface reactions and mutual interactions of adjacent crystal planes on average surface properties.

EN17028Metal removal by pine bark compost using a permeable reactive barrier device at laboratory scale

Javier Cancelo-González, Diego Martiñá-Prieto, Daniel Hernández-Huerta and María T. Barral
pp. 310-318

Environmental context. Permeable reactive barriers are a developing technology to clean up contaminated groundwater. The contaminant plume moves through a reactive material placed below ground that retains or degrades the pollutants. This study shows that pine bark compost strongly adsorbs and retains metals, mostly by interaction with the organic matter of the compost, and thereby serves as a suitable reactive filler material to clean up contaminated groundwater.

EN16213Assessing the optimal conditions for surface-mediated disinfection of Influenza A virus solutions

Ilaria Mannelli, Davide Janner, Francesc Sagués and Ramon Reigada
pp. 319-326

Environmental context. Transmission of viruses is related to their survival while being outside the host body. By means of experimental and computational simulations we assess the optimal conditions for virus deactivation upon contact with particularly functionalised substrates. These results constitute the basis for the design of new surfaces with high antiviral activity that can be important in public or sensitive environments such as in hospitals where the contamination and spreading of viruses are a critical issue.

EN17102Adsorptive removal of ammonium ion from aqueous solution using surfactant-modified alumina

Tien Duc Pham, Thi Trang Do, Van Lau Ha, Thi Hai Yen Doan, Thi Anh Huong Nguyen, Thanh Duc Mai, Motoyoshi Kobayashi and Yasuhisa Adachi
pp. 327-337

Environmental context. Ammonium ion, an inorganic pollutant in agricultural land, can induce eutrophication, impacting on water quality. We investigate the adsorption of ammonium ion on surfactant-modified alumina and demonstrate highly efficient removal of ammonium ions by the alumina from two agricultural water samples. Adsorption mechanisms are also proposed based on adsorption isotherms, surface modification and the change in surface charge.

EN17003Foam placement for soil remediation

Henri Bertin, Estefania Del Campo Estrada and Olivier Atteia
pp. 338-343

Environmental context. Soil pollution is an important concern and remediation techniques, especially in situ techniques, should be studied. We investigate a new technique based on foam generation and placement inside the porous soil to improve the pollutant extraction. This technique could be useful when the soils are heterogeneous because it allows a complete soil sweeping.
