Tannins in white wines were determined by reduction of the Folin-Ciocalteu reagent, extraction of the phosphomolybdenum blue produced into chloroform in the presence of a tetraalkylammonium salt, and thermal lens spectrometry (TLS). The TLS setup was pumped with a diode-array laser (60 mW, 818...
Jar test experiments with kaolin/river water indicated that all of the tannin coagulants were able to enhance particle settling significantly, although the quebracho tannin coagulants were slightly more efficient than the spruce tannin coagulants. Since the phenolic groups play the major role in the...
Stains due to the water supply: staining contaminants in water. Causes & sources of stains traced to the building water supply or supply piping: what are the sources of black, brown, green, red, yellow, or other stains in or caused by the building water
High-allochthonous-organic-matter-containing water bodies support trophic webs because bacterioplankton provide an alternative energetic base for the zooplankton, as possibly occurs in shallow lakes of the Salado-River basin, characterised by cyclic hydrologic periods alternating between draught and flooding ...

Compounds that act as tannins in forming complexes with proteins and other macromolecules can be divided into four groups, i.e., according to chemical structure, molecular weight, water solubility, and tannin action. The two major structural groups of tannins include the condensed tannins and the ...
