Phytoremediation of 137 Cs from low level nuclear waste using Catharanthus roseus

摘要: Remediation of radionuclides has been carried out using the phytoremediation technology. The green plants have screened for uptake potential radionuclide and found that Catharanthus roseus high in particular 137 Cs. Low level nuclear waste (LLNW) collected from effluent treatment plant, BARC characterized physico-chemical presence traces radionuclides. LLNW was spiked with 3.7×10 4 kBqL ―1 activity C. were grown (i) LLNW, (ii) Cs (iii) control. radio activities measured solution at intervals 0, 1, 2, 3, 6, 8 15 days triplicate set experiment. harvested after growth. depletion to be 19, 21, 24, 38, 60 76% days, respectively. bio-accumulation roots shoots plants. higher (998 kBq g dw) as compared (735 dw). radionuclide- Cs, shoot via active transport root, shows efficiency potentiality remediation radionuclide. will remediate contamination LLNW. can also made applicable effective present
