Abstract

In this study, the synthesis of a new chelating polymer through a reaction from the Drug Metoclopramide with Aldehyde (Salicylaldehyde). The characterization of the Monomer Schiff base was detected by (FT-IR),(C.H.N.S), and (1H-NMR) Techniques, then the Monomer Schiff base with (0.02 mol) of (Bisphenol A) and (0.2g) of para-formaldehyde. To the reaction mixture, (20ml) of formaldehyde and (15ml) of tetrahydrofuran are added. The potential of hydrogen is raised to pH=9.5 by adding 5% sodium hydroxide solution (polymerization) the chelating polymer was confirmed by (FT-IR). The effectiveness of the synthesized polymer was validated through its evaluation as a chelating agent for several toxic metal ions found in water, including Pb2+, Cu2+, Ni2+, and Co2+, using a batch processing method. The chelating polymer prepared from drug material shows higher results, The highest affinity of polymer to attach with Ions was achieved with Pb2+. Finally, the ability of the polymer to recover and separate from Ions was detected thereby the Pb2+ Ion had the highest value in the recovery process with (%85.3) meanwhile the Cu2+ was the lowest value in the recovery processing with a value of 50% from all amount. Activation of the polymer was also achieved by a Hydrochloride solution.
