Selective Adsorption and Detection of Heavy Metals from Aqueous Media using An Efficient Schiff-Base Resin (Polymethylene-bis(2-methoxy-1-napthaldehyde),m- xylenediimine

Abstract The Present study examine the synthesis of a novel compounds Schiff base bis (2-methoxy-1-napthaldehyde) m-xylenediimine, and Schiff based resin Polymethylene bis (2-methoxy-1-napthaldehyde),m-xylenediimine (PMBMNMXD).After the preparation of synthesized material were identified and characterized by different instrumental techniques for evaluate structure and surface morphology. The synthesized compounds were characterized via different spectroscopic techniques; (CHN), (FT-IR),(TGA),(EDS),(SEM), and (XRD) analysis. The synthesized resin has high adsorption capacity, stability and high efficiency, especially for metal ions. The synthesized material was used for uptake studies with Ni(II) and Cr(VI) ions. The optimum conditions were calculating by different parameters used to describe the effects of uptake including initial concentration, temperature, time, and pH through batch adsorption methods Schiff based resin will be used in adsorbents for removal of toxic metals from aqueous solution and wastewater treatment. The kinetic studies isothermal, thermodynamic and stability parameters will be studied and application of the proposed method on environmental water samples. The sorption results were used to examine different sorption isotherms like, Langmuir, Freundlich and kinetic studies such as, pseudo first order kinetics and pseudo second order kinetics. The slope and linear plot was used to evaluate the sorption isotherms. The polymeric resin PMBMNMXD was used for removal of Cr (VI) and Ni(II) ions in real water samples from different agricultural cities of Sindh (Province of Pakistan) such as Sanghar, Nawabshah, Kotri, and Jamshoro. The synthesized resin, PMBMNMXD were beneficial for industry because of their extraordinary adsorption properties for specific metal ions.
