Investigation of Heavy Metals Adsorption (Cd and Pb) in Aqueous Solution on the Suaeda aegyptiaca and the Adsorption Isotherm

The presence of heavy metals in the environment, especially in the water create many health problems. Effective technology for the removal of heavy metals using different  methods that are attractive from an economic standpoint, the availability and high power in remove the rest of their advantages. The aim of this study is to investigate the uptake of heavy metals (Cd and Pb) by the Suaeda aegyptiaca of the aquatic environment in the area is available as an absorbent. An experimental study was performed by dried Suaeda aegyptiaca of Jiroft (south of Iran) as absorbents. Batch experiments were performed at room temperature on a synthetic sample. The effects of absorbent dose, contact time, initial concentration of heavy metals absorption isotherms were determined and discussed. The results of the Suaeda aegyptiaca plant leaves absorb more lead than cadmium but with more energy will be absorbed. Readily available plant leaves in area and inexpensive absorbent according to the results of this method can be as a practical method to remove heavy metals from industrial waste water can be used.
