From:PLoS ONE (Vol. 8, Issue 7) Peer-ReviewedIntroduction The amount of sodium present in the body controls the extracellular volume. In advanced renal failure, sodium balance becomes positive and the extracellular volume expands, and this leads to adverse...
-
From:Power Engineering (Vol. 101, Issue 3) Peer-ReviewedCon Edison, New York's largest utility company, took a new approach to ion exchange in the water treatment tanks at its East River Station, replacing the screen-covered outlet laterals in one of its anion tanks with...
-
From:Journal of Analytical Chemistry (Vol. 70, Issue 1) Peer-ReviewedA novel ion imprinted polymer (IIP) material has been synthesized for mercury ion. The IIP material is applied to the solid phase extraction (SPE) of [Hg.sup.2+] from complex matrixes including water and fish samples....
-
From:LC-GC North America (Vol. 28, Issue 5) Peer-ReviewedWaters' Protein-Pak high-resolution ion-exchange columns are designed for the analysis of intact biomolecules including monoclonal antibodies, recombinant proteins, DNA/RNA, and vaccine components. According to the...
-
From:Polymer Engineering and Science (Vol. 60, Issue 12) Peer-ReviewedIn this research work, the synthesis and characterization of new ion exchange membranes made from sulfonated polyether sulfone (S--PES) crosslinked by aminated PES (NH2--PES) crosslinking reagent have been investigated...
-
From:Advanced Coatings & Surface Technology (Vol. 14, Issue 7) Peer-ReviewedAsymmetric and composite membranes capable of selectively separating one component of a gaseous or vapor mixture from another component are well known in the industry. For commercial operations, such membranes must be...
