Abstract:

 Problem statement: The uptake and recovery of lead ions were 
investigated by using agarose gel polymers. Approach: The experimental 
results showed that the agarose gel were effective in removing Pb (II) from solution. 
Biosorption equilibrium was approached within 4 h. Pseudo second-order was applicable 
to all the sorption data over the entire time range. Results: 
The sorption data conformed well to both the Langmuir and the Freundlich isotherm 
model. The maximum adsorption capacity (qmax) onto agarose gel was 115 mg g-1 
for Pb (II). The maximum uptake of metal ions was obtained at pH 2.0. At temperature 35°C, the biosorption of metal ions was found to be highest, with increase or decrease in temperature resulted in a decrease in the metal ions uptake capacity. Conclusion: Elution experiments were carried out to remove Pb (II) ions from loaded agarose gel and the bound metal ions could be eluted successfully using 0.1 M EDTA solution. The results suggest that agarose gel can be used as a biosorbent for an efficient removal of Pb(II) ions from aqueous solution.
