The College of Education for Pure Sciences, Department of Chemistry, has researched a doctoral thesis entitled
(Preparation and characterization of some chelate polymers derived from isophthalyl dichloride and studying their efficiency as adsorbent surfaces to treat pollution with some dyes and heavy elements from their aqueous solutions)
The thesis submitted by the researcher (Wissam Abdul Hassan Radhi) included the preparation of chelate polymers (thiourea amide polymers) derived from isophthalyl dichloride using ultrasound, characterizing these polymers using spectroscopic and thermal techniques, studying the use of the prepared polymers as adsorbent surfaces to remove the Bismarck brown Y and Congo red dyes and lead (II) and nickel (II) ions from their aqueous solutions and indicating the extent of the ability of these polymers to remove these pollutants. It also studied some of the factors affecting the adsorption process, including (temperature, acidity function, concentration of the two dyes, lead (II) and nickel ions (II)) In addition to finding the appropriate adsorption isotherms and determining their constants and knowing the adsorption kinetics of the two dyes and ions adsorbed on the surfaces of the prepared polymers, finding the thermodynamic functions ΔG, ΔH, ΔS for the adsorption process and studying the recovery of dyes and ions adsorbed on the polymer surfaces after their adsorption with dyes and ions. The prepared polymers showed good efficiency in adsorption of Bismarck brown Y and Congo red dyes and lead (II) and nickel (II) ions from their aqueous solutions, and the isotherms of the two dyes were subjected to the Langmuir equation, while lead (II) and nickel (II) ions.
