Investigations on water retention behaviour of deformable soils
2010The trend in modern unsaturated soil mechanics is to enhance the physical understanding of the soil water retention properties. It is agreed that the retention characteristics depend on the state of compaction and are related to the deformability of the media.

Retention behaviour of polystyrene oligomers in reversed-phase liquid chromatography
Journal of Chromatography A, 2002Reversed-phase liquid chromatography (RPLC) was employed to investigate the behaviour of low-molecular-mass polystyrene oligomers with three different end groups, n-butyl, sec-butyl, and tert.-butyl polystyrenes. Exothermodynamic retention studies on the polystyrene oligomers were carried out using a C18 stationary phase column and 100% methanol mobile

Influence of temperature on the retention behaviour of proteins in cation-exchange chromatography
Journal of Chromatography A, 1996The chromatographic behaviour of several amino acid derivatives, peptides and proteins has been investigated with the so called "tentacle-type" LiChrospher-100 SO3- adsorbent and an analogous poly(2-sulphoethylaspartamide) cation-exchange adsorbent, PolySulphoethyl A.

Retention behaviour of beta‐blockers in HPLC using a monolithic column
Journal of Separation Science, 2006AbstractThe chromatographic behaviour of a new HPLC‐stationary phase (Chromolith® RP‐18e) is described for separation of beta‐blockers. The effects of the different chromatographic conditions (buffer system, pH value, content of organic modifier, injection volume and flow rate) on the separation behaviour were studied.

Water retention behaviour of tailings in unsaturated conditions
2021Tailing dams are complex geotechnical systems comprising of an embankment and a basin containing the waste products from the mining processes. These structures are characterized by a wide surface exposed to the atmosphere whose interaction governs the position of the phreatic surface within the basin.

Retention behaviours and separation of carboxylic acids by ion-exchange chromatography
Journal of Chromatography B: Biomedical Sciences and Applications, 1998The use of high-performance suppressed ion chromatography for the separation of aliphatic carboxylic acids has become an attractive and viable method during the past years. This paper summarises and critically concludes that some new results have been achieved in separation and detection of low-molecular-mass organic anions.

On the fractal behaviour of water retention curves
2011Water retention curve (WRC) is analyzed by means of the fractal geometry approach. Three models accounting for the fractal distribution of either the pore and solid phase of unsaturated porous media have been considered. By using data collected during a field scale internal drainage, we determine the functional relationship between the WRC, and the ...

Carboxylic acids: prediction of retention data from chromatographic and electrophoretic behaviours
Journal of Chromatography B: Biomedical Sciences and Applications, 1998A review of the main results reached in the prediction of retention data of carboxylic acids, inferred by their chromatographic and electrophoretic behaviour, is presented. Attention has been focused on the main separation methods used in carboxylic acids analysis, that is ion-exclusion, anion-exchange, reversed-phase (RP) liquid chromatography and ...

Retention behaviour of carbohydrate oligomers in reversed-phase chromatography
Journal of Chromatography A, 1984The retetnio behaviour of starch and cellulose hydrolysates on alkyl-modified silica columns using aqueous eluents has been studied. The influence of eluent pH, addition of sodium chloride or alcohols to the eluent, pore diameter of the silica support and chain length of the alkyl modification were investigated.
