Chelation Ion Exchange Properties of 2, 4-Dihydroxyacetophenone-Biuret-Formaldehyde Terpolymer Resin

Pre-conditioning and Regeneration Requirements of Ground Gel Resorcinol Formaldehyde Ion Exchange Resin

Synthesis, Characterization and Ion-exchanging Properties of Novel Ion-exchange Resin Part-iii

The polyamine (PA) was prepared by condensation of 1,4-bischloromethyl benzene and benzidine. The PA was then treated with cyanuric chloride at 0°C followed by reaction with 5-amino-8-Hydroxyquinoline in THF in conc. NaOH (PH 9-10) at room temperature for 8 hrs. The resultant polymer designated as polyamine-s-triazine-5-amino8-Hydroxyquinoline (PATHQ) was characterized by elemental analysis, IR...

Drug release properties of polymer coated ion-exchange resin complexes: experimental and theoretical evaluation.

Although ion-exchange resins have been used widely as drug delivery systems, their exact release kinetics has not been reported yet. Usually only the rate-limiting step has been taken into account and the rest of the steps have been ignored as instantaneous processes. To investigate the exact release kinetics of polymer-coated drug/ion-exchange resin complexes for sustained drug delivery, the r...

Drug loading and release properties of ion-exchange resin complexes as a drug delivery matrix.

Complexes of ion-exchange resins and dextromethorphan (DM), a model drug, were prepared using different methods including a batch and a column method with different functional groups, ion-exchange capacity, degree of crosslinking, and resin particle size. Drug loading efficiency, release profiles, and scanning electron micrographs were also investigated. Most of the functional groups of resins ...

Biocompatibility research of a novel pH sensitive ion exchange resin microsphere

The main objective of this study was to investigate biocompatibility and provide in vivo pharmacological and toxicological evidence for further investigation of the possibility of pH sensitive ion exchange resin microsphere for clinical utilizations. Acute toxicity study and general pharmacological studies were conducted on the pH sensitive ion exchange resin microsphere we prepared. The genera...
