Removal of both N-nitrosodimethylamine and trihalomethanes precursors in a single treatment using ion exchange resins
(2017-11-01)
Drinking water utilities are relying more than ever on water sources impacted by wastewater effluents. Disinfection/oxidation of these waters during water treatment may lead to the formation of several disinfection ...

First purification of heparan sulfate disaccharides with an amine resin used as solid support for peptide synthesis
(Elsevier B.V., 2000-01-03)
For the first time, highly substituted benzhydryramine-resin (BHAR), a solid support used only for the peptide synthesis method was assayed successfully as an anion exchanger resin for fractionation of (-2)-, (-3)- and ...
Development of charged ion exchange resin-polymer ultrafiltration membranes to reduce organic fouling
(Elsevier Science, 2006-07-05)
This work deals with the performance of polymeric membranes charged with an ion exchange resin on the ultrafiltration (UF) of an oily suspension. The membranes were prepared by the phase inversion process from polysulfone ...
Polystyrene-type resin used for peptide synthesis: application for anion-exchange and affinity chromatography
(Elsevier B.V., 2005-03-25)
This paper deals with an unusual application for a copolymer of styrene-1 % divinylbenzene bearing high amount of aminomethyl groups for anion-exchange and affinity chromatography. The so-called aminomethyl resin (AMR), ...
Corrosion of steel drums containing cemented ion-exchange resins as intermediate level nuclear waste
(Elsevier Science, 2013-07)
Exhausted ion-exchange resins used in nuclear reactors are immobilized by cementation before being stored. They are contained in steel drums that may undergo internal corrosion depending on the presence of certain ...
Use of commercial anion-exchange resins as solid support for peptide synthesis and affinity chromatography
(Elsevier B.V., 2003-07-01)
This report demonstrates that due to the presence of residual reactive sites in their matrices, classical diethylaminoethyl-attaching commercial anion-exchanger resins such as DEAE-MacroPrep and DEAE-Sephadex A50 supports ...
