Abstract

In this study, a green chemistry approached was employed in
the preparation of Hyphaene thebaica
fiber grafted polyacrylic acid via microwave assisted method using potassium
persulfate as chemical initiator. The optimum percentage grafting 92% was
achieved under 5g concentration of acrylic acid, 0.2g concentration of
potassium persulfate (KPS) and 2 minutes reaction time.  The grafted sample was characterized using
the following techniques, FTIR, SEM and XRD. The prepared graft copolymer was
examined for adsorption of Pb (II) ions from aqueous solution in batch mode systems.
The adsorption parameters such as pH, initial metal ion concentration and
contact time were also studied. The Langmuir and Freundlich isotherm models
were applied to simulate the equilibrium adsorption experimental data. The
Langmuir model fitted well with experimental data with maximum adsorption
capacity (q_max) of 20.37 mg/g at 45 minutes. Higher regression
coefficient obtained confirmed the suitability of the Langmuir isotherm model
which assumed monolayer coverage on the adsorbent surface. The adsorption
studies revealed the efficacy of the grafted fiber for removal of Pb (II) ions
from dilute aqueous solutions.
