摘要
Polylysineresorcinol coated alumina nanotube has been synthesized based on Mannich reaction. Synthetic polymer has been obtained using lysine and resorcinol as monomer and p-formaldehyde as linker by condensation reaction. The nanosorbent was employed for cadmium adsorption from aqueous samples. Effective parameters on sorption process have been optimized with BoxBehnken design (BBD). Equilibrium time was 11 min as well as adsorption capacity was 220 mg g(-1). Regeneration of the sorbent was performed with HNO3 solution (0.5 mol L-1). The accuracy of the method was evaluated by determination of cadmium in various real samples.
