Removal of nitrite ions from aqueous solutions by cross-linked polymer of ethylenediamine with epichlorohydrin

Sorption of nitrate onto amine-crosslinked wheat straw: Characteristics, column sorption and desorption properties

“…The epoxy ethers are hydrolyzed and then the chains are cross-linked with ethylenediamine to produce diamine cellulose/hemicellulose ethers [18,19]. In the third step, the triethylamine is grafted onto the diamine cellulose/hemicellulose ethers and form the triethyl ammonium sites in an excess of epichlorohydrin [20].…”

Preparation of new types of anion exchange resins from agricultural by-products and their utilization in the removal of various toxic anions from solutions

“…The epoxy cellulose/hemicellulose ethers in G1 are hydrolyzed and then the side chains cross-link with EDA to produce G2 [16,17]. In the third step, the TEA is grafted onto the G2 to form the triethyl ammonium sites in G3 in an excess of epichlorohydrin [18].…”

Electrodeposition of Insulating Thin Film Polymers from Aliphatic Monomers as Transducers for Biosensor Applications

“…Addition of water in these media dramatically modify the voltammograms by generating an anodic wall, instead of the plateau observed previously, that appears at a lower potential particularly as the water concentration increases (Figure 3). (Saegusa et al, 1972), (Biçak et al, 1998) Raman spectroscopy discarded, from the mechanism, a possible formation of substituted hydrazine(s) due to the doubling of the radical formed after the loss of a proton and an electron. XPS spectra of L-PEI coating from EDA electropolymerization match well those already published (Beamson et al, 1992).…”
