Aerocellulose samples were placed in beakers with 30 mL of DI water containing 65% (w/w) of the cationic reagent (1.05 g CR-2000).
Conclusion: It was determined that, unlike other cationic reagents, the high transfection efficiency of HSA-PEI was not from the electronic effect but, instead, predominantly from its ligand effect.
The companies overlap in many markets, but the EU executive had particular concerns about their hold on the three sectors: the production of persulfates, cationic reagents and hydroxy monomers.
The company develops and manufactures both standard and tailor-made anionic, amphoteric and cationic reagents. Its flotation collectors, marketed under the Atrac, Lilaflot, Armoflote, Armeen and Ethomeen brand names, are mainly used for the flotation of non-sulphide minerals such as apatite, barite, calcite, dolomite, feldspar, fluorspar, kyanite, magnesite, potash, pyrochlore, quartz, scheelite, wollastonite and zinc oxides.
