Polyelectrolyte multilayers (PEMs) based on biopolyelectrolytes are highly appealing for the surface engineering of biomaterials and the tuning of cell response and phenotypes for biomedical applications. However, cell a...

Changes of bentonite surface structure under the influence of direct microwave irradiation during adsorpion of Cu2+ from concentrated solutions were investigated by X-ray and EDS analysis. The microwave treated bentonite...

In this work we demonstrate the feasibility to couple adsorption with Fenton and photo-Fenton process to separate and mineralize crystal violet (CV) dissolved in water. Montmorillonite (MMT) and Iron modified Montmorill...

Abstract In this study, an environmentally friendly nanocomposite was synthesized and comprehensively characterized for its potential to adsorb Pb2+ ions and malachite green dye (MG) from aqueous solutions. The composite...

The adsorption of Sr(II) cations by Boron-doped TiO2 was investigated.  The adsorbent samples were obtained by liquid-phase sol-gel method using the aqua complex precursor [Ті(ОН2)6]3+‧3Cl- and modifying reagent h...

In this paper, the effect of SnO2 impurity on the surface charge and adsorption properties of TiO2 samples is investigated. The experimental value of the zero charge point for TiO2 with 3%, 6% and 12% of SnO2 equals 3.53...

In the present paper the mesoporous TiO2 with chemosorbed carbonate groups was investigated as an adsorbent for the removal of Zn2+ and Ba2+ cations from aqueous solutions. The dependence of the adsorption values of Zn2+...

Abstract This study explored the adsorption of methylene blue (MB) from aqueous solutions using natural clay as an adsorbent. The effects of contact time, initial dye concentration, adsorbent dosage, and pH were systemat...

The adsorption of proteins on carbon-based materials is a complex and multifaceted process critical to applications in biotechnology, medicine, environmental science, and materials engineering. This review comprehensivel...

This paper presents a study of adsorption and vibrational features of folic acid, using surface-enhanced Raman scattering (SERS). A gold-capped silicon nanopillar (Au NP) with a height of 600 nm and a width of 120 nm was...

Carbonyl sulfide (COS) is a dangerous gas produced from fossil fuel combustion and petrochemical procedures, so proper adsorbent and sensors are required for removal and detection. In this work, we study by Density Funct...

The adsorption of picloram on Fe Oxide Pillared Clays (PILC) as a possible basis for the development of adsorbent materials for the remediation of polluted environments was studied. To this end, after characterizing PILC...

"A novel nanoremediation concept, which is based on in situ trapping of organic contaminants by adsorption and catalytic oxidation in combination with oxidants such as hydrogen peroxide is presented. In earlier works we ...

Paracetamol, an over the counter analgesic and antipyretic drug, causes hepatic and renal tubular necrosis at higher doses ingested accidentally, or intentionally. The situation worsens clinically upon the ingestion of p...

Na Amazônia o cromo é empregado principalmente na indústria de couro e de madeira, sendo responsável por vários problemas de saúde porque é tóxico para os seres vivos. A remoção de cromo de efluentes industriai...

Aims: (i) To determine the aflatoxin B1 (AFB1) adsorption and desorption dynamics in the presence of Lactobacillus rhamnosus RC007 under simulated transit of AFB1 at each gastrointestinal tract (GIT—saliva, stomach and...
