Patent number: 10501341Abstract: Cross-linked polymeric resins from anilines linked together with polyamine alkyl chains. A process for producing the cross-linked polymeric resins by Mannich-type polycondensation of anilines and diaminoalkanes linked together by an aldehyde and subsequent basification. In addition, a method for removing heavy metals, such as Pb (II) and As (V) from aqueous solution via contacting and treatment with the cross-linked polymeric resins.Type: GrantFiled: May 30, 2019Date of Patent: December 10, 2019Assignee: King Fahd University of Petroleum and MineralsInventors: Othman Charles Sadeq Al Hamouz, Oluwafemi S. Akintola, Tawfik Abdo Saleh Awadh

Publication number: 20190300390Abstract: A cross-linked polymeric resin which contains reacted monomer units of an aniline, a diaminoalkane, and an aldehyde, and which is functionalized with at least one dithiocarbamate moiety. A process for producing the cross-linked polymeric resin whereby an aniline and a diaminoalkane are linked together by Mannich-type polycondensation reactions with an aldehyde. The resulting Mannich-type polycondensation product is converted into the cross-linked polymeric resin through functionalization of one or more amine functional groups with dithiocarbamate moieties. A method for removing heavy metals, such as Hg(II), from an aqueous solution, whereby the cross-linked polymeric resin is contacted with the aqueous solution, and the heavy metal is thus adsorbed onto the cross-linked polymeric resin.Type: ApplicationFiled: June 17, 2019Publication date: October 3, 2019Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Oluwafemi S. AKINTOLA, Tawfik Abdo Saleh Awadh, Mazen Mohammad Khaled, Othman Charles Sadeq Al Hamouz
