Chromium VI and Fluoride Competitive Adsorption on Different Soils and By-Products
(MDPI, 2019)Chromium (as Cr(VI)) and fluoride (F−) are frequently found in effluents from different industrial activities. In cases where these effluents reach soil, it can play an important role in retaining those pollutants. Similarly, ... -
Development of new analysis methods for the study of molecular aggregation and adsorption
(2021)Molecular aggregation processes as well as adsorption to interfaces between media of different polarity are necessary for many natural phenomena and industrial applications. From the formation of cell membranes to the ... -
Efficient Separation of Heavy Metals by Magnetic Nanostructured Beads
(MDPI, 2020)This study reports the ability of magnetic alginate activated carbon (MAAC) beads to remove Cd(II), Hg(II), and Ni(II) from water in a mono-metal and ternary system. The adsorption capacity of the MAAC beads was highest ... -
Enhanced oil recovery with nanofluids based on aluminum oxide and 1-dodecyl-3-methylimidazolium chloride ionic liquid
(Elsevier, 2022)Surface-active ionic liquids (SAILs) have multiplied the possibilities of surfactant enhanced oil recovery (EOR) methods. Among their multiple promising features, the possibility of functionalization and their stability ... -
Fluid interface calorimetry
(Elsevier, 2021)Hypothesis: Amphiphilic molecules spontaneously adsorb to fluid polar-nonpolar interfaces. The timescale of such adsorption depends on the molecular size and structure of the solute. This process should be accompanied by ... -
Novel Magnetic Nanostructured Beads for Cadmium(II) Removal
(MDPI, 2019)This study presents an effective magnetic separation method for cadmium removal, based on the use of a novel nanostructured material as an adsorbent. This adsorbent involves the incorporation of magnetite nanoparticles ... -
Recovery and concentration of antioxidants from winery wastes
(MDPI, 2012)Grape and wine byproducts have been extensively studied for the recovery of phenolic compounds with antioxidant activity and a variety of biological actions. The selective recovery and concentration of the phenolic compounds ... -
Relevance of sorption in bio-reduction of amoxicillin taking place in forest and crop soils
(Elsevier, 2022)The fate of antibiotics reaching soils is a matter of concern, given its potential repercussions on public health and the environment. In this work, the potential bio-reduction of the antibiotic amoxicillin (AMX), affected ... -
Retention of the Antibiotic Cefuroxime onto Agricultural and Forest Soils
(MDPI, 2021)Antibiotics in wastewater, sewage sludge, manures, and slurries constitute a risk for the environment when spread on soils. This work studies the adsorption and desorption of the antibiotic cefuroxime (CFX) in 23 agricultural ... -
Short and long term orange dye effects over AOB and anammox activities
(2016-09-07)In this research work the effects of orange azo dye over ammonia oxidizing bacteria (AOB) and anammox bacteria activities were tested. Adsorption onto the biomass was detected with both types of biomass however no biological ... -
Study of Adsorption and Flocculation Properties of Natural Clays to Remove Prorocentrum lima
(MDPI, 2015)High accumulations of phytoplankton species that produce toxins are referred to as harmful algal blooms (HABs). HABs represent one of the most important sources of contamination in marine environments, as well as a serious ... -
Tetracycline and Sulfonamide Antibiotics in Soils: Presence, Fate and Environmental Risks
(MDPI, 2020)Veterinary antibiotics are widely used worldwide to treat and prevent infectious diseases, as well as (in countries where allowed) to promote growth and improve feeding efficiency of food-producing animals in livestock ... -
Unsupervised bubble calorimetry analysis: surface tension from isothermal titration calorimetry
(Elsevier, 2022)Hypothesis: The injection of air into the sample cell of an isothermal titration calorimeter containing a liquid provides a rich-in-information signal, with a periodic contribution arising from the creation, growing and ... -
Utilization of Composts for Adsorption of Methylene Blue from Aqueous Solutions: Kinetics and Equilibrium Studies
(MDPI, 2020)Utilization of composts as low-cost adsorbents is an important application in the field of environmental remediation, but these materials have not yet been extensively used for dye removal. In this work, we have studied ...
