In this study, (E)-2-((2-hydroxynaphthalen-1-yl)methyleneamino)pyridin-3-ol(HNMAP) compound was immobilized on sporopollenin
of Lycopodium clavatum spores. The obtained structure was characterized by infrared spectroscopy
(IR) and scanning electron microscopy (SEM). This newly synthesized compound has been used as an adsorbent in
the separation of heavy metals. Batch method was used to separate Cu (II), Co
(II) and Ni (II) ions from waste waters. In
addition, different experimental parameters such as pH, concentration, duration
of interaction and concentration were selected to effectively separate heavy
metals from aquous solution and waste waters. The experimental results were
applied to Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm
equations. Thermodynamic parameters such as
free energy (∆G0), entropy (∆S0) and enthalpy (∆H0)
were calculated from the experimental
results to explain the mechanism of the sorption. As a result, this adsorbent
has been successfully used to separate Cu (II), Co (II) and Ni (II) from
aqueous solutions and waste water.
