Nickel Remove by means Ion Exchange Resins

[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...

Quantitative determination of urine sodium by means of ion exchange resins.

The method for quantitative determination of serum sodium as described by Vanatta and Cox (1) is adaptable to determination of urine sodium. However, wider variations in sodium and potassium concentrations, and the presence of ammonia and other interfering substances, necessitate certain modifications of the procedure. Apparatus and Reagents-The items of apparatus needed for the determination o...

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...
