Kinetics of leaching and distribution of Uranium and associated water quality Parameters in baran district of rajasthan

Abstract

The present study was focused on assessment of gamma radiation level near newlinethe water sampling sites, analysis of uranium, heavy metals (Cu, Zn, Fe, Co, Pb and newlineAl), water quality parameters viz. pH, TDS, EC, DO, ORP, salinity, temperature, newlinesulphate, chloride, nitrate, phosphate, carbonate, bicarbonate in groundwater newlinesamples, soil leachate solution and their correlation with uranium, kinetics of newlineleaching of uranium from soil to groundwater, factor affecting of leaching capacity newlineof uranium and adsorption isothermostec collected from different locations viz. Anta, newlineBaran, Kishanganj, Shahbad, Mangrol, Atru, Chabra and Chhipabarod tehsils of newlineBaran district of hadoti region of Rajasthan, India. My research work divided in six newlinechapters. newlineChapter 1 Briefly describes the natural radiation exposure and its newlinecharacteristics, uranium and its chemistry in the environment, distribution of newlineuranium in the environment, uranium speciation and uranium mobility in soil for newlinebioavailability, leaching of uranium from soil to ground water and uranium pollution newlinein groundwater. The objective of the thesis is briefly described highlighting newlineevaluation of uranium in groundwater in the study area and its comparison with newlinevarious standards: 30and#956;g/l (USEPA, 2000), 60 and#956;g/l (AERB), and 30 and#956;g/l (WHO, newline2011). The expected contribution from the proposed study has also been included at newlinethe end of the chapter. newlineChapter 2 Deals with different materials, methods, equipments and newlinedescription of study area. Standard protocols are applied for estimation of water newlineparameters, Uranium and gamma radiation during the entire research work. newlineChapter 3 Reports results of assessment of gamma radiation level near the newlinewater sampling sites, assessment of uranium, physico-chemical parameters and their newlinecorrelation in groundwater. The analytical data for all water quality parameters and newlineuranium are cross checked with respect to recommendations given by newlineBIS/WHO/AERB limits to identify the pollution level.
