Removal of aqueous metals from wastewater using porous functional heterocyclic aromatic amines

In this work, the applicability of poly aromatic amines (PAA) for the removal of gold, copper and palladium from various water samples has been investigated. Batch experiments were performed to realize the effect of relative nitrogen/carbon composition on the ability of PAA for removal of aqueous metals to achieve quantitative separation of metal. Besides, the effect of monomer structures on the morphology of polymerized aromatic amines was studied. Several polymerized aromatic amines were prepared by oxidative chemical. ICP-MS was used to determine the content of matals in the initial and final sample solutions to calculate metal uptake. The morphology was examined using scanning electron microscopy. Besides, the C/N ratio of the polymers was investigated by element analysis (EA).
