Abstract
A crosslinked resin made up of polymerized units of a linear polyamine with at least 3 primary and/or secondary amine functionalities and a bisacrylamide. The crosslinked poly mers are porous spherical particles with a BET surface area in the range of 50-120 m²/g. A method of the synthesizing the crosslinked polymer is specified. A method for using the crosslinked resin as an adsorbent material in removing pollutants including organic dyes (eg Congo red, Rhod amine B) and heavy metals from an aqueous solution or an industrial wastewater sample is also described.
