Abstract
In this workN2,N6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide (DPD), was synthesized via reaction of 2-aminothiazole and 2,6- pyridinedicarboxylic acid in n-methylpyrrolidine. The obtained (DPD) was characterized with nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FT-IR) spectroscopy, and elemental analysis. Finally, a novel magnetic nanoadsorbent was synthesized by modification the surface of Fe3O4 nanoparticles by N2,N6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide. The prepared magnetic nanoadsorbent was successfully used for removal of Zn2+ and Cd2+ ions from industrial wastes and the effects of the affecting parameters such as pH, possible interfering ions, contact time, concentration of target ions, background electrolytes and temperature were investigated. The maximum adsorption capacities of Zn2+ and Cd2+ were found to be 149.2 and 112.4 mg g−1, respectively. The required times for quantitative removal of Zn2+ and Cd2+ were 30 and 45 min, respectively. Appropriate characteristics of the proposed nanoadsorbent such as high adsorption capacity, stability, reusability, easy synthesis and easy separation, make it suitable adsorbent for practical removal of Zn2+ and Cd2+ ions  from industrial wastes.
