in this study, the neutral monosaccharide composition of the extracellular polysaccharide (eps), extracted from thermal bacillus, was determined by liquid chromatography-mass spectrometry and high performance liquid chromatography. our analysis indicated that the eps consisted of rhamnose, mannose, galactose, glucose, fructose, arabinose and xylose. in addition to the neutral sugars in the eps,...
(109)High-molecular Electrolytes.VII. Anomalies of Alginic Acid and Its Sodium Salt as Electrolytes.
Preparation and Proton Conductivity of Polymer Electrolytes Based on Alginic Acid and 1,2,4-Triazole
The interaction of estradiol, estrone, progesterone and testosterone with environmentally relevant concentrations of Aldrich humic acid, alginic acid and tannic acid was studied using solid-phase microextraction (SPME). Since bulk organic matter and certain hormones such as estradiol and estrone contain dissociable functional groups, the effect of pH on sorption was investigated as this will in...
Organic conditioning films have been shown to alter properties of surfaces, such as hydrophobicity and surface free energy. Furthermore, initial bacterial adhesion has been shown to depend on the conditioning film surface properties as opposed to the properties of the virgin surface. For the particular case of nanofiltration membranes under permeate flux conditions, however, the conditioning fi...
