Abstract: A method of removing a metal ion from water is disclosed. The method includes treating the water with a nanocomposite to absorb the metal ion with the nanocomposite, forming a polymer-metal ion composite and removing the polymer-metal ion composite from the water. The nanocomposite includes aluminum oxide dispersed in a matrix of an uncrosslinked graft copolymer that includes a chitosan backbone and side chains of poly (itaconic acid) grafted to the chitosan backbone. The chitosan backbone has a plurality of amino groups that are acetylated by itaconic acid.

Abstract: Disclosed herein are clusters compounds that include at least one substituted amine sulfate and at least one substituted amine bisulfate molecule. The substituted amine sulfate molecule and the substituted amine bisulfate molecule may each include an ammonium moiety with at least one alkyl substituent. Optionally, the alkyl substituent can include 1 to 20 carbon atoms, 1 to 10 carbon atoms, or 1 to 6 carbon atoms. For example, the alkyl substituent can be a methyl, ethyl, propyl, butyl, or pentyl group. In some examples, the substituted amine sulfate molecule and the substituted amine bisulfate molecule each include an ammonium moiety with at least two alkyl substituents. Optionally, the two alkyl substituents are the same. Alternatively, however, the two alkyl substituents can be different.
