Determination of Vitamin B6 by Synthetic Ion-Exchange Resin

The Determination of Total Base of Serum by Ion Exchange Reactions of Synthetic Resins

Measurement of total base of blood serum supplies information indispensable for the complete description of the electrolyte balance in many physiological and pathological states. Older methods involving separate analyses of the principal cations or their conversion to sulfates, with subsequent determination of sulfate, were time-consuming, while the latter was of doubtful accuracy. More recentl...

Esterification Reaction Kinetics Using Ion Exchange Resin Catalyst by Pseudo-Homogenous and Eley-Ridel Models

This work deals with kinetics and chemical equilibrium studies of esterification reaction of ethanol with acetic acid.  The esterification reaction was catalyzed by an acidic ion exchange resin (Amberlyst-15) using a batch stirred tank reactor. The pseudo-homogenous and Eley-Rideal models were successfully fitted with experimental data. At first, Eley-Rideal model was examined for heterogeneous...

Removal of Chromium (vi) from Synthetic Wastewater Using Spectra/gel Ion-exchange Resin

Strong anion exchange resin (Spectra/Gel IE 1x8) has been investigated as adsorbent for the efficient removal of Cr(VI) ions from synthetic wastewater solutions. Batch experiments were conducted with initial Cr(VI) ions concentration ranging from 25-300 mg/L. Different parameters influencing Cr(VI) adsorption process such as; solution pH, Cr(VI) and adsorbent concentration and contact time were...

Synthesis of neopentyl glycol and ethylene glycol esters by fatty acids in the presence of acidic ion exchange resin catalyst

A most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. In this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...

Extraction of Carbon Dioxide from Sea water by Ion Exchange Resin Part II: Using Strong Base Anion Exchange Resin
