Description:
Potential of plants to remove radionuclides/toxic elements from soils and solutions can be successfully applied for removal of important radionuclides such as strontium-90 (^9^0Sr) and cesium-137 (^1^3^7Cs). When uptake of ^1^3^7Cs and ^9^0Sr by Calotropis gigantea plants incubated in distilled water spiked with the radionuclides either alone or in combination was studied, it was found to have a high efficiency for the removal of ^9^0Sr, with 90% being removed from solutions (5x10^3kBql^-^1) within 24h of incubation. However, in case of ^1^3^7Cs, about 44% could be removed from solutions (5x10^3kBql^-^1) at the end of 168h of incubation. Accumulation of ^9^0Sr and ^1^3^7Cs was higher in roots compared to shoots. The plants could remediate both ^9^0Sr and ^1^3^7Cs when they were added together to the solution. When two months old plants were incubated in low level nuclear waste, 99% of activity disappeared at the end of 15 days. The present study suggests that C. gigantea could be used as a potential candidate plant for phytoremediation of ^9^0Sr and ^1^3^7Cs.
