Experimental measurements have been made on the batch ion exchange of Ca(II) and Mg(II) from potassium chromate solution using cation exchanger of Amberlite IRC 748 as K+ form. The ion exchange behavior of two alkaline-earth metals on the resin, depending on contact time, pH, temperature and resin dosage was studied. The adsorption isotherms were described by means of the Langmuir and Freundlic...

Ondansetron Hydrochloride (ODH) is 5-HT3 receptor antagonists and is used for pediatric formulation. It is an antiemetic drug given in treatment of nausea and vomiting. The bitter taste of the drug and having shorter half-life and needed frequent administration which reduces patient compliance. Hence, need was felt to deliver ODH to the patients, once a day to improve the patient compliance of ...

Graphitic carbon nanocapsules, nanosheets and nanoplates were selectively obtained via a solid-state pyrolysis route from various ion-exchange resin-iron complexes.

A method for growing Streptomyces griseus LP-16 in fermentors and extracting and purifying geosmin, using an ion-exchange resin, is described.

A study of regeneration of the ion exchange resins using a sub-critical mixture of CO2-H2O solution was reported. The experimental data were obtained by measuring the outlet concentration of ions Cd eluated from a column packed with a commercial ion exchange resin Amberlite IRC-86 until the effluent reached the input concentration. The adsorption isotherm was also reported. The correlation of t...

Ion exchange resins are water-insoluble, cross-linked polymers containing salt-forming groups in repeating positions on the polymer chain. Bitter cationic drugs get adsorbed on to weak cationic exchange resins of carboxylic acid functionality like Indion 204, Indion 234 and Tulsion 335 to forms non-bitter complexes. The present investigation aims at taste masking of the bitter clarithromycin us...

Recycling treatment of cable insulation resin generated from electric wires and cables was investigated. Conventional insulation PVC contains a lead component, tribase, as a thermal stabilizer and lead removal is necessary to recycle this PVC as insulation resin. This paper describes a solid surface adsorption method using ion exchange resin to remove the fine lead containing particles from PVC...

MAGEE. T. V., and D. F. ZINKEL. 1986. A rapid method for diterpene resin acid analysis of pine needle oleoresin. Can. J. For. Res. 16: 1107-1109. A method for diterpene resin acid analysis has been developed for pine oleoresin samples at the submilligram level. The method utilizes the removal of acidic components by a micro-DEAE-Sephadex ion-exchange column and analysis of the recovered resin a...
