Workshop
Department of Chemistry, College of Education for Pure Sciences, University of Karbala, organized a workshop entitled (Synthesis of a new nano-copolymer and its application in removing pollutants), delivered by Eng. NS. Amir Salem Mayali. The workshop aimed to synthesize a new nanopolymer by esterification process, characterize this new nanopolymer by (FT-IR, 1HNMR, 13C NMR, AFM and XRD), and measure the size of the particles of this new nanopolymer by (AFM, XRD) techniques. New to remove pollutants by the adsorption process with three dyes (malachite green, reactive red, and dispersed blue).
The lecturer also showed that the nanopolymer produced by the reaction of phthalic anhydride and pentarithritol was distinguished by techniques (FT-IR, 1H-NMR, 13CNMR, AFM and XRD). AFM results showed that the average size of the polymer nanoparticle is 97.23 nm, while XRD was 97.19 nm. This proves that the prepared polymer is nanoscale, and the XRD pattern indicates that the presence of solid aromatic rings originating from phthalic acid, leads to stiffer structures, which should be more prone to crystallization than the fully aliphatic polymer. Polymer synthesis in the formation of a branched polymer containing carbonyl groups, since there is an excess of carbonyl groups with respect to alcohol groups. A greater amount of phthalic acid indicated that the molecular motions, due to the stiffness of the aromatic rings, should facilitate packing of the polymer chains into crystal lattices. This polymer was used as an adsorbent for water pollutants using three pigments (active red, malachite green and diffuse blue) as the adsorbents.
