Abstract

The present study is on adsorption of Fe(II) ions by Activated Syringodium Isoetifolium
Leaves Nano Carbon. It uses batch adsorption techniques. The influence of contact time, initial
concentration, dosage of adsorbent and effect of solution pH were investigated. The equilibrium
adsorption data were correlated with Langmuir, Freundlich, Temkin, Dubinin-Radushkevich,
Hurkins-Jura, Halsay, Radlich-Peterson, Jovanovic and BET isotherm models. The isotherm
studies of RL values showed that the adsorption process was favorable. Thermodynamic
parameters such as ∆H0
, ∆S
0
and ∆G0 were evaluated. The data indicate that, the adsorption was
spontaneous and is an endothermic nature. Adsorption kinetics was tested with pseudo- secondorder,
Elovich model and intra – particle diffusion models. Kinetic studies indicate an adsorption
pseudo-second-order reaction. This study shows that intra-particles played a major role in the
adsorption of Fe(II) ions mechanism. The Activated Syringodium Isoetifolium Leaves Nano
Carbon has high adsorption capacity and adsorption rate for the removal of Fe(II) ions from
aqueous solution
