  • Crosslinked polymers and a method for heavy metal ion removal
    Patent number: 11530289
    Abstract: A crosslinked polymer that is in the form of a Mannich polycondensation product including reacted units of a cyclic diaminoalkane, an aldehyde, and bisphenol-S or melamine. Also disclosed is a method for removing heavy metals from an aqueous solution by contacting the aqueous solution having an initial concentration of the heavy metal with the crosslinked polymer to form a mixture, and filtering the mixture to obtain an aqueous solution having a reduced concentration of the heavy metal compared to the initial concentration.

  • Crosslinked polydithiocarbamate, synthesis thereof, and use for removing heavy metals
    Patent number: 10494472
    Abstract: Crosslinked polydithiocarbamates based on 1,3,5-triazinane cores linked to pyrrole-dithiocarbamates via alkyl chains. A process for preparing these crosslinked polydithiocarbamates via a Mannich-type polycondensation of diaminoalkane, paraformaldehyde and a pyrrole compound, which is followed by additional modification of the pyrrole moiety to a pyrrole-dithiocarbamate. A method for removing heavy metals, such as Cd(II) from an aqueous solution or an industrial wastewater sample with these crosslinked polydithiocarbamates is also described.
