Dynamics of BaCl2-NH3 adsorption pair [PDF]

, 2009
To obtain accurate kinetics of adsorption pairs, dynamic tests of a composite adsorbent material (BaCl2 impregnated into a vermiculite matrix) and ammonia were performed on small samples under isothermal conditions and on a larger quantity in a ...

Hydrophobic interaction chromatography [PDF]

, 2011
Most proteins and large polypeptides have hydrophobic regions at their surface. These hydrophobic ‘patches’ are due to the presence of the side chains of hydrophobic or non-polar amino acids such as phenylalanine, tryptophan, alanine and methionine ...

Influência da matéria orgânica na adsorção do fungicida triadimenol pelo solo Influence of organic matter on the adsorption of triadimenol fungicide by soil

Química Nova, 2002
The adsorption of triadimenol (1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol) on soil samples with varying contents of organic matter was studied. The adsorption was described by means of the Freundlich's isoterm.
