Özet:

 


In this work, silver nanoparticles (AgNPs) were
biosynthesized using Cyprus acacia (Acacia
cyanophylla) leaf extract as reductant agent; the biosynthesized AgNPs were
characterized by DLS, FT-IR, SEM, EDX, and XRD. Then, the single and multistage
batch adsorption of Basic Red 46 dye (BR46) onto AgNPs were studied and the
optimum conditions were determined as follows: initial pH of 7.0, initial dye
concentration of 200 mg/L, temperature of 35 oC, and adsorbent
concentration of 1.0 g/L. For BR 46-AgNPs adsorption, the equilibrium was
defined by Langmuir isotherm model and the adsorption kinetic data were best
described by the pseudo second order kinetic model. From Weber-Morris model, it
was concluded that only intraparticle mass transfer was effective on the
adsorption of BR 46 by AgNPs. It was obtained from the thermodynamic studies
that the studied adsorption system was exothermic, induced, and decreasing in
randomness of adsorbed species.
