In Vitro Binding of Iron With the Cation-Exchange Resin Sodium Polystyrene Sulfonate
Annals of emergency medicine, 1996Co-Authors: Timothy A. O'connor, S M Watling, J C Gehrke, Barbara A Gruner, C W GehrkeAbstract:Abstract Study objective: To investigate the ability of the Cation-Exchange Resin sodium polystyrene sulfonate to bind iron from ferrous sulfate solutions, along with the effects of pH on binding. Methods: We performed a series of in vitro experiments in which various concentrations of iron and sodium polystyrene sulfonate were combined and free ferrous iron was measured with the use of a colorimetric assay. Results: Sodium polystyrene sulfonate bound iron from ferrous sulfate solutions at pH 2 and pH 7. Slightly less binding of free ferrous iron was demonstrated in experiments performed at pH 7 than in those performed at pH 2. At pH 2, 98% of iron was bound; at pH 7, 95% of iron was bound. Conclusion: Sodium polystyrene sulfonate may be a useful therapy in acute iron poisoning once safety and efficacy are determined with the use of in vivo models.

esterifiCation of oleic acid with ethanol catalyzed by sulfonated Cation Exchange Resin experimental and kinetic studies
Energy Conversion and Management, 2013Co-Authors: Yuwang Jiang, Kaian Sun, Jincheng DingAbstract:Abstract This paper investigated the effects of ethanol to oleic acid molar ratio, reaction temperature, catalyst loading, water content and catalyst recycling on sulfonated Cation Exchange Resin in a stirred batch reactor under atmospheric pressure. When the esterifiCation was carried out with an ethanol to oleic acid (42.4 g) molar ratio of 9:1, reflux of ethanol at 82 °C, 20 g of catalyst and 8 h of reaction time, the oleic acid conversion rate reached approximately 93%. A pseudo-homogeneous kinetic model for describing the esterifiCation of oleic acid with ethanol by the sulfonated Cation Exchange Resin was developed on the basis of laboratorial results. The kinetic model can well predict the oleic acid conversion.

Improvement of epothilone B production by in situ removal of ammonium using Cation Exchange Resin in Sorangium cellulosum culture
Biochemical Engineering Journal, 2007Co-Authors: Sang Woo ParkAbstract:Abstract A Cation Exchange Resin was added at different stages in the growth of Sorangium cellulosum cultures to remove excess ammonium, which has a negative influence on the production of the anticancer agent, epothilone. When 8 g L −1 of Cation Exchange Resin were added at the mid-death phase, the ammonium removal reached 83% and the maximum production of epothilone was 14.3 mg L −1 , which was 2.6 times greater than that of the control culture.
