Mitigating uranium in groundwater: prospects and limitations.
Removal of uranium(VI) by zerovalent iron has been suggested as a feasible pathway to control uranium contaminations in seepage waters. Available information in the literature however presents discrepant evidence on the process responsible for the mitigation effect. On basis of an EH-pH diagram of uranium and iron, it is outlined that these discrepancies may be explained by the aqueous chemistr...
متن کاملUranium removal from groundwater by natural clinoptilolite zeolite: effects of pH and initial feed concentration.
Adsorption of uranium (VI) on a natural clinoptilolite zeolite from Sweetwater County, Wyoming was investigated. Batch experiments were conducted to study the effects of pH and initial feed concentrations on uranium removal efficiency. It was found that the clinoptilolite can neutralize both acidic and low basic water solutions through its alkalinity and ion-exchange reactions with U within the...
متن کاملEstimation of Distribution Coefficient of Uranium and its correlation with soil parameters around Turamdih Uranium Tailings Pond
Predicting the transfer of radionuclides in the environment for normal release, accidental, disposal or remediation scenarios, in order to assess exposure, requires the availability of important generic parameter values. One of the key parameters in environmental assessment, is the solid liquid distribution coefficient, K d , which is used to predict radionuclide–soil interaction and subsequent...
متن کاملEnhancement of natural background gamma-radiation dose around uranium microparticles in the human body.
Ongoing controversy surrounds the adverse health effects of the use of depleted uranium (DU) munitions. The biological effects of gamma-radiation arise from the direct or indirect interaction between secondary electrons and the DNA of living cells. The probability of the absorption of X-rays and gamma-rays with energies below about 200 keV by particles of high atomic number is proportional to t...
متن کاملHigh levels of uranium in groundwater of Ulaanbaatar, Mongolia.
Water samples collected from 129 wells in seven of the nine sub-divisions of Ulaanbaatar were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) using Clean Lab methods. The levels of many trace elements were found to be low with the average concentrations (ranges in brackets) being 0.9 (<0.1-7.9) μg/L for As; 7.7 (0.12-177) μg/L for Mn; 0.2 (<0.05-1.9)μg/L for Co; 16 (<0.1-686) ...
