TL;DR: The polyethylenimine as complexing agent was used to study the complexation-ultrafiltration (CP-UF) process in the selective removal of Cu(II) from Ni( II) contained in aqueous media, and process selectivity was observed.
TL;DR: In this article, the authors evaluated the adsorption capacity of palm shell activated carbon (PSAC) to remove copper ions from aqueous solutions and found that the results of batch and continuous adaption experiments showed high adsorptive capacity of the untreated PSAC to adsorb copper ions at pH 3 and 5, respectively, while the presence of complexing agents, boric and malonic acids, did not improve copper uptake.
TL;DR: The solid block detergents of as discussed by the authors used a mixed inorganic and organic sequestrant composition, which successfully softens service water used in manufacturing aqueous detergent from the composition, but also obtains substantially improved organic soil removal on dishware or flatware.
Abstract: Solid block alkaline detergent compositions are disclosed comprising a source of alkalinity, and other detergent additives including sequestrants. The solid block detergents of the invention used a mixed inorganic and organic sequestrant composition that successfully softens service water used in manufacturing aqueous detergents from the composition, but also obtains substantially improved organic soil removal on dishware or flatware. The solid block detergents of the invention comprise large masses of the chemical ingredients having a weight of greater than about 500 grams in a solid block product format that is typically dispensed using a spray on water dispenser that creates an aqueous concentrate that is used in a washing machine.
TL;DR: An amine polymer includes first and second substituents bound to amines of the polymer, the first substituent includes a hydrophobic moiety and the second substitution includes a quaternary amine-containing moiety as mentioned in this paper.
Abstract: An amine polymer includes first and second substituents bound to amines of the polymer. The first substituent includes a hydrophobic moiety. The second substituent includes a quaternary amine-containing moiety. A method for binding bile salts of bile acids in a mammal includes orally administering to the mammal a therapeutically-effective amount of the amine polymer.
