Determinación de cationes en agua potable del cantón de Grecia, Costa Rica por absorción atómica
(Sedes Regionales, 2014)
Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils
(06/01/2001)
Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ...
Cationic Dialdehyde Nanocellulose from Sugarcane Bagasse for Efficient Chromium(VI) Removal
(Amer Chemical Soc, 2020-03-30)
Cellulose-based materials are the most widely used green materials because of their abundance, sustainability, biodegradability, and functionalizability. The capability of cellulosic materials as adsorbents and coagulants ...
Determination of the degree of substitution of modified chitosan by cyclic voltammetry at water/dichloroethane interface
(Elsevier, 2014-12)
The electrochemical behavior of the cationic polymer chitosan-gtmac (Ch-GTMAC), at the polarized water / 1,2-dichloroethane interface was studied. This polymer was obtained by nucleophilic reaction of chitosan (Ch) with ...
Stream acidification and base cation losses with grassland afforestation
(American Geophysical Union, 2008-07)
Afforestation of natural grasslands with fast-growing pine and eucalyptus species is increasing globally, but little is known about its effect on ecosystems and watersheds and, ultimately, the quality of water resources. ...
Role of pH in partitioning and cation exchange of aromatic amines on water-saturated soils
(08/04/2001)
Predicting the reversible interactions between aromatic amines and soil is essential for assessing the mobility, bioavailability and exposure from contaminated sites. Reversible sorption mechanisms of aniline and α-naphthylamine ...
Effect of sugar and sorbitol on the formation of low methoxyl pectin gels
(Elsevier Sci LtdOxfordInglaterra, 2000)
Competitive solvation of the imidazolium cation by water and methanol
(Elsevier B.V., 2015-03-02)
Imidazolium-based ionic liquids are widely used in conjunction with molecular liquids for various applications. Solvation, miscibility and similar properties are of fundamental importance for successful implementation of ...
The effect of chain length on the melting temperature and size of dialkyldimethylammonium bromide vesicles
(Elsevier B.V., 2006-07-01)
Differential scanning calorimetry (DSc) and dynamic light scattering (DLS) were used to obtain the gel to liquid-crystalline phase transition temperature (T-m) and the apparent hydrodynamic radius (R-h) of spontaneously ...
