Abstract: Barberry is well known and naturally adapted in Iran, and it has been extensively used as a medicinal plant in traditional medicine. The fruit of the barberry is used in medicine to treat liver, neck and stomach cancer, for purification of the blood and for breath freshness. Iran is the main center for distribution of genus Barberry vulgaris and Barberry integerrima and one of the richest countries in the world as regards genetic resources of medicinal and wild unknown plants that some of them are export . We have studied on potential ability of Barberry integerrima residue potential as an adsorbent of heavy metal . B. integerrima barberry fruits were collected in 2015 from Qaen in south Khorasan province in the north-east of Iran and put in contaminated soil samples by heavy metals. Aerial parts of growing coriander in every ten days in companion of B. integerrima fruits residue in the soils were separated in 30 days and digested by wet method according the standard protocol for measuring Cadmium ,Chrome (III) and (VI) , Nickel and Lead. Mean values were calculated, and analysis of variance (ANOVA) and Student’s t-test were performed. The results of present study revealed adsorption capacity of Cr (VI), Cr(III), Pb and Cd by barberry residue was investigated in a batch system by considering the effects of various parameters like contact time, initial concentrations, pH , temperature, absorbent dose. The results of this study revealed that B. integerrima fruit barberry residue can accumulate high level of lead, Cadmium and Chrome (VI) and (III) in a short time and their uptake rate by vegetable and edible plant is significantly affected by their concentrations in the contaminated soil (p<0.05). A contact time of 10 days by B. integerrima was found to be optimum and 89.2% Cr (VI), 78.9% Cr(III), 95.6% Pb and 43.6% Ni was remained in soil while a few amounts of these heavy metals being uptake by edible vegetable – coriander . Experimental results showed that low cost bio-sorbent was effective for the removal of pollutants from soil.
