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...
متن کاملEffects of Weak and Strong Cation Exchange Resins on Moisture Uptake Behavior of Ranitidine Hydrochloride
The aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable H+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. Drug resin complexes (DRC) were prepared and evaluated for the percentage of moisture gain when placed in a humidity c...
متن کاملSulfonated Resins
Ion-exclusion chromatography (IEC) has been widely used in the separation of carboxylic acids, finding applications in the analysis of food and beverages, pharmaceuticals, biological samples, and acid rain samples.1 The retention mechanism of carboxylic acids in ion-exclusion chromatography has also been investigated in many studies, and the factors which affect retention can be divided into th...
متن کاملQuantitative determination of azure A in urine.
HE INTRODUCTION OF the carboxylic acid cation exchange Amberlite XE-96 (or IRC-50) Azure A resin’ as the medium for hydrogen ion exchange in place of the quininium exchange resin has simplified greatly the determination of gastric acidity without intubation (1). Solvent extraction and fluorimetry are no longer required. The amount of blue dye excreted in the urine is readily measured by visual ...
متن کاملCharacters 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...
