Cation exchange reactions provide a robust and versatile method for tuning the composition, morphology and functionality of nanostructured materials. By selectively substituting cations within a ...

Resodec, § the exchange resin used in the patients described in this report, is an acrylic polymer of heavy molecular weight, whose carboxylic radicals can readily adsorb and release cations to which ...

THE clinical application of cation-exchange resins provides a new means of controlling the sodium content of the body. Several reports on their uses and limitations in edematous states have been ...

Researchers have developed a tool that allows farmers to quickly and affordably test soil samples, get results in real-time, and obtain fertilizer recommendations.

Agriculture advisers are encouraging farmers to explore the option of placing biochar on their fields to help improve soil ...

Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...

The Acclaim ® Mixed-Mode WCX-1 is a novel, high-efficiency, silica-based column, manufactured by bonding a specially designed proprietary ligand with both hydrophobic and weak cation-exchange ...

A slight modification to Bascomb's procedure for determining cation exchange capacity makes it applicable to gypsic soils even when the gypsum content is as high as seventy percent. The modification ...

Ion exchange (IEX) chromatography is a technique that is commonly used in biomolecule purification. It involves the separation of molecules on the basis of their charge. This technique exploits the ...
