Is there a method which can be used to estimate uranium in water. Any suggestions will be helpful.
not sure what you mean by 'estimate' - can be measured routinely by ICP/MS
if you do not initially care about the isotopic distribution, try a photometric analysis, much less expensive than ICP. See http://pubs.acs.org/doi/abs/10.1021/ac50028a022?journalCode=ancham
you can also use ion exchange specific for uranium then do a total count and then compare to a uranium standard
Uranium in the water sample can be determined by different methods such as ICPMS, ICPAES, Fluorescence, spectropohotometry etc. But the to employed depends on the concentration of uranium in the sample and also interfering elements present in sample.
Zaynab Aly: Australian Nuclear Science and Technology Organisation, Australia - You can measure measure (not estimate) uranium concentration accurately using inductively coupled plasma mass spectroscopy (ICP-MS) or inductively coupled plasma optical emission spectroscopy (ICP-OES) depending on the concentration of uranium in water. For very low concentrations (< 1mg/L) opt for ICP-MS. For higher concentrations use ICP-OES. ICP-OES is easier to use but both require preparation of multiple standards and the addition of internal standard(s) as well as inclusion of international standard in the analytical batch. ICP-OES has a large range of up to 100 mg/L. See my paper - Z. Aly and V. Luca, “Uranium extraction from aqueous solution using dried and pyrolyzed tea and coffee wastes”, J. Radioanaly. Nucl. Chem., Volume 295, issue 2, (2013) pages 889-900. Doi: 10.1007/s10967-012-1851-6
There is a review paper published in Talanta,77 (2008) 9–20, attached herewith.

To determine Uranium in water, I mean the activity of U-234 and U-238 you can fellow the procedure publised by Eichrom Technology in which you find all the steps: preconcentration of sample, co-precipitation, seperation and purification of Uranim and finaly the source of Uranium by electrodeposition then measurement by alpha spectrometry

Hello there,
The best and quickest methods to determine uranium in water are by ICP-OES and ICP-MS. ICP-OES gives you total uranium in water while ICP-MS can give relevant isotope ratios. Both methods can be automated and be done while you do other jobs around. They both require operational standards, controls, replicates as well as international standards in a batch for accuracy and validation purposes. ICP-OES is quicker than ICP-MS; and since I cannot envisage matrix problems in water I recommend both these methods depending on the amount of uranium in water. If the concentration of uranium in water is less than 500ppb, then ICP-MS is the best choice. For higher concentrations of uranium ICP-OES is the obvious choice.
In case of analysis of uranium in water samples, the reliability of the technique used and quality of the measurements depend on strict adherence to each step of sampling, preservation of samples, time interval between sampling and analysis, and on the methodology adopted, and not solely on the person who analyzes the samples and the laboratory or technique used.
Fission track estimation of uranium in water is a simple and reliable method.
In my profile there is a similar question and answers therein. Kindly check it.
What is the most reliable method for the determination of uranium in water?
Moreover, there are interesting letter to editor articles by me and open reviews related with uranium..
As far as I know that Laser Fluorimetry is the method(UA-3 Analyser,SCINTREX) for analysis of uranium in water. Water contains ppb level of U, this low content of U in water is estimated only by method of Laser Fluorimetry. For rock samples which contains U in ppm to % level , they are estimated by Conventional Pellet Fluorimrtry.
The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) released the new report on 8 February 2017, which is freely downloadable from
http://www.unscear.org/docs/publications/2016/UNSCEAR_2016_Report.pdf
This "UNSCEAR 2016" report has four annexes. Of these, Annex D is dedicated to uranium, and its section II.A.3 especially deals with uranium levels in water.
