Abstract
Introduction

Lead is one of the most important metal ions that has many disadvantages for the environment and organisms, especially humans. One of the most effective methods for causing lead from aqueous solutions is the use of biological adsorbents. The purpose of this study was to investigate the biological biosorption of lead (II) from aqueous solutions using Padina algae.

Materials and Methods

Padina algae was collected from Bushehr coastal and dried in an oven at 70 ° C for 24 hours, then adsorption experiments were carried out at pH(2-9), contact time (15-150)minutes, different amounts of biomass(0.1-2) and initial concentration(10-50) mg/L of the solution and Isotherm also.

Results

The results showed that the removal efficiency of lead ion on the bio-absorbent Padina increased with increasing contact time ( lowest at 15 minutes with 22% and highest at 120- 150 minutes with 75%) and Biosorbent dose ( the highest at 10mg/L concentration with 92%) decreased with an increasing initial concentration of the solution. It also increases the removal efficiency by increasing the pH and finally reaches the maximum at pH = 6. The data obtained from the study of isotherm adsorption showed that the mechanism of adsorption of lead ion (II) to the bio-absorbent of the Padina follows well Langmuir isotherm.

Conclusion

Padian biomass can be used as an adsorbent for the removal of lead ions (II) from aqueous solutions as a cheap absorbent and can be prepared under various conditions.
