Heavy metal ion adsorbent |
| abstract |
Cross-linked terpolymers made up of phenol, diaminoalkane and formaldehyde monomeric units. The cross-linked terpolymers are synthesized via a Mannich mechanism in n-heptane, characterized with multiple spectroscopic techniques, scanning electron microscopy and powder X-ray diffraction, and are also investigated for their Pb2+ adsorption capacity and thermodynamic properties. A method of removing Pb2+ ions from an aqueous solution or a wastewater sample with these cross-linked terpolymers is also described. |
