Electro-Decontamination of Spent Ion Exchange Resins Contaminated with Iron Oxide Deposits under Dynamic Conditions

[Ion exchange resins].

Ion exchange resins have been used to help formulate pharmaceuticals since the late 1950's. During that time they have proved to be safe and effective excipients and are now used in many commercial formulations throughout the world. In this article we will look at some of the common problems faced by formulators and how using ion exchange resins may be able to solve them. Ion exchange resins ar...

Deodorizing experiments with ion exchange resins.

In a previous report (1), the differences in the carbon number of the lower fatty acids contained in cutaneous secretions such as axillary sweat, smegma, and dandruff, were considered as factors responsible for the difference in odor between osmidrotic and non-osmidrotic subjects. Besides these there are ammonia constituents and volatile salts (trimethylamine, methylamine) which may take part i...

Exchange of mercury between atmosphere and vegetation under contaminated conditions.

Adsorption and desorption of mercury was studied under laboratory conditions using moss (Sphagnum girgensohnii) and Rye grass (Lolium perenne) at different temperatures. Desorption was also studied in a transplantation experiment. The adsorption was rapid and strong for both plant species at different temperatures (+10 to +60 degrees C) and exposure times (1 h, 1 month) while the evaporation wa...

Ion exchange resins: catalyst recovery and recycle.

Ion-exchange resins as drug delivery carriers.

There are many reports in the literature referring to the utilization of drug bound to ion-exchange resin (drug-resinate), especially in the drug delivery area. Ion-exchange resin complexes, which can be prepared from both acidic and basic drugs, have been widely studied and marketed. Salts of cationic and anionic exchange resins are insoluble complexes in which drug release results from exchan...
