Abstract: The efficacy of various plants in eliminating different heavy metal contaminants, particularly Lead and Cadmium is a major concern nowadays due to the vast soil pollution in many countries around the world especially Iran. In this research determination of the potential ability of dried aerial parts of Ferulago Angulara in companion of black tea residue for cleaning up contaminated soil and their probable capability of adsorption different heavy metals (Nickel, Lead and Cadmium) was investigated. F. Angulara were collected in August 2015 from Kermanshah Province, Iran and samples was identified by the Herbarium of Faculty of Pharmacy, Pharmaceutical Sciences Branch, Islamic Azad University (IAUPS).The contaminated soil by Ni, Cd and Pb was put into the sites in a way that F. Angulara and tea leaves residue were mixed in different percentages up to 20%-20% (W/W) in examined soils individually and both of plants together in order to find the effect of companion residues in possible potential biosorption . Metal contents were detected by Atomic Absorption Spectrophotometer by wet digestion method in every 10 days during 60 days in Research Laboratory. Results indicated that the rate of heavy metals uptake by F. Angulara is significantly affected by the presence of dried tea leaves residues (p<0.003 ) . Tea leaves are more capable in absorbing nickel than F. Angulara and when we put both together in 20%-10% (tea leaves/ F. Angulara) the potential of taking up nickel significantly enhanced (p<0.01 ) .The Cadmium and Lead uptake rates by F. Angulara areal parts are significantly affected by pH and companion in the contaminated soil (p<0.001). The results of this research concluded that F. Angulara and tea residue in the contaminated soil have suitable ability for adsorption method and removing more Lead and Nickel in pH <7 after 20-60 days of study.
