BIOACCUMULATION OF RHENIUM IN GREEN PLANTS. NEW POSSIBILITY FOR ITS RECOVERY
Abstract
It is known that rhenium is easily accumulated in green leaves and plants, its amount in them exceeding many times its occurrence in the earth’s crust (7x10-8\%). We have established that rhenium is accumulated in the chlorophyll, preferably as Mg(ReO4)2. Laboratory experiments with green geranium (Pelargonium) planted in soil spiked with rhenium (1 mg Re per g of soil) reveal that in the first 7 days after the soil is spiked rhenium content in the leaves is 20 mg g-1 and after 21 days it is increased to 100 mg g-1. Leaves of acacia, birch, poplar, etc., collected in the vicinity of ore processing works have been analyzed for Re content. The results show increased Re content in the analyzed samples (up to 3600 times) as compared to its natural spread. Rhenium content in leaves of oak, birch and poplar collected in unpolluted areas appear to be also slightly increased (5-50 times) as compared to its content in the earth’s crust. The results obtained should be advantageous in development of technological scheme for rhenium recovery from soil and waters in the vicinity of ore dressing works using suitable green plants.
