Possible role of organic matter in radiocaesium adsorption in soils [PDF]

open access: yes, 2002
The aim of this review is to examine the hypothesis that organic matter decreases the adsorption of radiocaesium on clay minerals. The factors that determine radiocaesium mobility and bioavailability in soil are briefly outlined to show why a ...

Interactions between cadmium and lead with acidic soils: Experimental evidence of similar adsorption patterns for a wide range of metal concentrations and the implications of metal migration [PDF]

open access: yes, 2012
The importance of high- and low-affinity surface sites for cadmium and lead adsorption in typical European and Asian soils was investigated. Adsorption experiments on surface and deep horizons of acidic brown (Vosges, France) and red loess soils (Hunan ...

Chemical valorization of waste polyacrylonitrile polymers via shuttle catalysis

open access: yesNature Communications
Acrylonitrile-based polymers are widely used in industrial and consumer settings, contributing to the growing amount of plastic waste. Yet, their chemical recycling has largely been neglected, partly due to the potential release of harmful gases such as ...

Modified orange peel waste as a sustainable material for the adsorption of contaminants [PDF]

open access: yes, 2023
World orange production is estimated at 60 million tons per annum, while the annual production of orange peel waste is 32 million tons. According to available data, the adsorption capacity of orange peel ranges from 3 mg/g to 5 mg/g, while their water ...

Surface pre-coating of talc particles by carboxyl methyl cellulose adsorption : study of adsorption and consequences on surface properties and settling rate [PDF]

open access: yes, 2006
This paper investigates the adsorption of different sized carboxyl methyl cellulose (CMC) onto talc particles (adsorption isotherm, adsorption reversibility), its consequences on the particles properties (electrophoretic mobility and surface wetting) and

Sequestration of hexavalent chromium and paracetamol from water using deoiled hemp stem-twigs and roots and activated carbon

open access: yesEnvironmental Challenges
In the present study, deoiled hemp stem-twigs and roots and activated carbon were used to remove chromium and paracetamol. The hemp-based materials were characterized, and the surface area of the activated carbon samples increased more than 55-fold ...

Polyelectrolyte adsorption

open access: yesJournal de Physique, 1988
The adsorption of uncharged polymers is, due to numerous efforts over past decades, fairly well understood. Some insight exists into the structure of the adsorbed layer, and the effect of the important parameters molecular weight, solvency and polymer/surface interaction has been investigated. Theory and experiment are beginning to converge.

Adsorption Kinetics of Polymer/Surfactant Mixtures at an Expanding Air/Water Interface [PDF]

open access: yes, 2013
The dynamic adsorption mechanisms of a range of polymer/surfactant mixtures have been studied at the expanding air/water interface created by an overflowing cylinder.

Adsorption and release of BMP-2 on nanocrystalline apatite-coated and uncoated hydroxyapatite/b-tricalcium phosphate porous ceramics [PDF]

open access: yes, 2009
The association of bone morphogenetic proteins (BMPs) with calcium phosphate bioceramics is known to confer them osteoinductive properties. The aim of this study was to evaluate the surface properties, especially regarding recombinant human BMP-2 (rhBMP-
