Synthesis of chelate polymer between 2,4 -diamino-6-phenyl-l,3,5 triazine and EDTA as sequestrant of metal ions

Abstract AR

In this research the new condensed polymer was synthesized by poly condensation of EDTA and 2,4-Diamino-6-Phenyl 1,3,5 triazine as a chelating polymer which was complexed with metal ions such as Ti,Co,Cr,Ni,Fe ions.

These prepared complexes were characterized by elemental analysis and infrared and Ultraviolet spectroscopies.

The physical properties were measured.

Intrinsic viscosities were calculated by using Ostwald viscometer.

Introduction : Chelate - forming polymers are polymers that incorporate cl^ating (multi dentate) ligands by covalent bonding.

Ion- exchange resins represent the most prominent class of chelating polymer and generally contain multifunctional ligands attached at one point or in the network or forming either intra molecular chelating groups (1"3\ The range of chelating ligands of interacting with ion solution is very wide and many have been bonded to polymers.

Some of chelates are 8-hydroxy quinoline, hydroxamic acid, examines , pol^mines acrylic acid type poly vinyl pyridine (4"7) .^p™ximately five tones of heavy metals from industrial manufacturing are added every year to our nation's water, which makes clean up a high priority Lead (Pb), mercury (Hg) and cadmium (Cd) in particular are extremely toxic to the majority of living organisms8'؛'’ .

Recently, the use of chelating polymers for remediation of water and soil has attracted much attention (g\ The pharmacologic effects of EDTA calcium disodium are due to the formation of chelates with divalent and trivalent metals.
