Removal of Ni, Cu and Zn from a Contaminated Soil using Different Brassica Species
The remediation of heavy metal (Ni, Cu and Zn) in contaminated soil by different Barley and Brassica nigra (IC – 247)]. Species of Barley and Brassica were grown in contaminated soil and after washing with tap water [seed was collected from Krishi Anusandhan Bhavan Pusa Delhi]. The soil were mixed different amendment [FYM, ssp, CaCO3 and FYM+CaCO3]. and metal was applied at the rate of 0 and 20 Zn +10 Cu + 2.5 Ni (mg/kg soil) in the form of hydrated salts of concerned metal viz ZnSO4.7H2O, NiSO4.6H2O, and CuSO4. 5H2O. After harvesting the plant were treated with di acid and prepare sample with double distal water. The observed concentration of Cu [2.78mg to 4.78mg], Ni [3.52mg to 6.43mg] and Zn [3.39mg to 5.5mg] respectively, in species of Rai (B.nigra) and observed concentration of Cu [3.95 mg to 5.49 mg], Ni [3.72 mg to 5.68 mg], Zn [4.09 mg to 5.76 mg] respectively in species of Barley.
