Title : Synthesis of Novel Polymer Grafted Triazole Macrocycle and Study Its Ability to Recover Lead Ion.

Abstract :

The multivalent binding of heteroatoms inside the macrocycle to metals are gained interests. To synthesis functionalized macrocycles based on 3,5-dihydroxybenzoic acid core, a common nucleophilic substitution reaction of phenolic hydroxyl with propargyl bromide under basic condition was applied. The cyclization was achieved with click reaction of dipropargyls with diazides in presence of Copper chloride (I) and sodium ascorbate in dichloromethane. From the other side, the polyvinyl chloride was converted to its polyvinyl azide derivative and finally reduce the azide to its corresponding polyvinyl amine. Finally, the crafted polymer is obtained by amide formation. The intermediates are characterization by the NMR, FTIR spectroscopy, and mass spectrometry, while the FESEM, EXD, XRD, DSC techniques are used for confirm the morphological shape and thermal stability further studied the synthesized polymer. The removal of lead ions is performed by Batch methodology using atomic absorption in different experiment conditions, which is indicated the removal of such metals effective and the recyclability is highly sufficient.
