Study using Vetiver grass to treat radioacitve pollution at Sin Quyen copper miner area, Lao Cai Province

Abstract

The article introduces the research results of using Vetiver grass in radioactive environment treatment (water waste, mud waste) in Sin Quyen copper mine area, Lao Cai province. After 30 days, uranium absorption efficiency reached 77.4% and thorium 83.5%, the total alpha and beta activity of the water dramatically declined, alpha treatment efficiency reached 95.3% while beta treatment efficiency reached 93.7%. The model of radioactive pollution treatment by Vetiver showed high efficiency, simple operation. Therefore, it is very promising to apply the treatment of radioactive sludge, radioactive waste sludge in the process of exploiting and processing Sin Quyen copper ore in particular, the areas of radioactive mineral mining in general.
