| description | The potential of Annona muricata leaf powder as an adsorbent for the removal of
Pb(II) in the aqueous solution was investigated. The Annona muricata leaf powder
was characterized before the adsorption using Fourier Transform Infrared (FTIR)
spectrophotometer and Thermogravimetric analyzer (TGA). The zero point charge for
the adsorbent surface was determined and the data shows that the value for pHzpc is
6.3. The effect of pH, sorbent dosage, initial concentration and contact time were
investigated. The maximum uptake of Pb(II) was at pH 6 with 64.57 mglg. The
absorption equilibrium was established after 30 minutes. The adsoprtion of Pb(II) by
Annona muricata leaf powder increased with its initial concentration. Pseudo-second
order showed the best fitting with high correlation (R2 = 0.999). It was found that the
adsorption fits well with Langmuir isotherm equation. The maximum adsorption
capacity for Langmuir Isotherm was found at 192.31 mg/g. The study suggested that
Annona muricata could be an efficient sorbent for Pb(II) removal. |
