Adsorption and desorption behavior of Gd(III) ionon macroporous weak acid resin (MWAR) had been investigated.The influence of operational conditions such as contact time, initial concentration of Gd(III) ion, initial pH of solution and temperature on the adsorption of Gd(III) ion had been examined. Experimental data were exploited for kinetic and thermodynamic evaluations ...

AIMS To determine the effects of anaerobic electron acceptors on 3-methylindole (3-MI) and 4-methylphenol (4-MP) production in swine lagoon enrichments and Clostridium scatologenes ATCC 25775. METHODS AND RESULTS Swine lagoon sediment was incubated anaerobically in tryptone-yeast extract medium with (10 mmol l(-1)) Na(2)SO(4), KNO(3), dimethyl sulfoxide or Fe(III). With Fe(III), 3-MI and 4-MP...

An octasaccharide with high affinity for antithrombin, isolated after partial deaminative cleavage of heparin, was previously found to have an L-iduronosyl-N-acetylglucosaminyl-6-O-sulfate nonreducing terminal disaccharide unit. After digestion of this octasaccharide with alpha-L-iduronidase and N-acetylglucosamine-6-sulfate sulfatase, two fractions, with high and low affinity for antithrombin,...

Multiphoton excited luminescent properties of water-soluble Eu(III) and Tb(III) complexes with derivatives of dipicolinic acid functionalized with a polyoxyethylene pendant arm and terminal groups, [Eu(L(OMe))(3)](3-), [Eu(L(NH2))(3)](3-), and [Tb(L(OH))(3)](3-), as well as of binuclear helicates with overall composition [Ln(2)(L(CX))(3)] (X = 2, 5) are investigated. Characteristic emission fro...
