A Facile Preparation of Flavones Using Nonaqueous Cation-Exchange Resin

Carboxylic cation exchange resin effects in dogs.

Reports describing trials of exchange resins in removing cations from the gastrointestinal tract of experimental animals have been limited to toxicity studies and to measurements of the relative magnitudes of the oral intake and the stool output (1-3). In the experiments presented in this paper changes in serum, urine, and stool components, as well as the external and internal balances of certa...

Characters of Kinetic and Equilibrium of Adsorption of Eu(III) by an Cation Exchange Resin

The sorption and desorption behaviors of Eu(III) from aqueous solutions with cation exchange resins containing carboxyl groups (D155 resin) were studied in terms of varied Eu(III) concentration, adsorbent dosage, pH, contact time and temperature. Batch shaking sorption experiments were carried out to evaluate the performance of D155 resin in the removal of Eu(III) from aqu...

Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent,

Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent, developed by Tanaka et al. in 1994, has been employed to monitor the quality of environmental water samples such as acid rainwater and river water, to analyze body fluid samples such as saliva, and to evaluate water purification by photocatalytic materials.1–8 One advantage of...

Clinical effects of a cation-exchange resin (Zeo-Karb 225).

A cation-exchange resin artificial kidney: development and metabolic studies.

are relatively few, and generally are related to either inadvertent transfusion of incompatible blood or the outcome of some severe form of injury. The latter may follow a surgical operation or be the result of massive trauma incurred during combat. The consequent renal insufficiency is often temporary in nature, and efforts are directed at prolongation of life by sustaining the patient through...
