Synthesis and Characterization of the Schiff Base-on Functionalized Novel Sporopollenin Microcapsule and Its Use for Effective Adsorption of Cu (II)

Cu (II) ions, which cause serious diseases such as cancer and liver damage, have an important place, especially in water pollution. To effectively remove these deadly copper ions from aqueous solution, the synthesis of a new functionalized sporopollenin microcapsules (Sp-CPTS-HNMAA) to be used adsorbent was aimed. Schiff base (HNMAA), functionalize surface sporopollenin, obtained result reaction 2-Hydroxy-1-naphthaldehyde glycine characterized by 1H 13C NMR. The synthesized Sp-CPTS-HNMAA microcapsule successfully FTIR, XRD, SEM techniques. effects initial concentration, temperature, pH, anion, contact time, dose were researched adsorption experiments. equilibrium calculated 92.73%, with time 150 min, ion concentration 30 mg L-1, pH = 6, maximum Cu(II) removal 0.03 g dose. capacity Langmuir isotherm found 32.57 g-1. Adsorption kinetic studies indicated that it fits pseudo-second-order model. results thermodynamic show is reversible, spontaneous, endothermic, also showed on chemical process.
