  Uranium concentrations were estimated of 11 phosphate fertilizer samples collected during 2016-2019 and also of 15 Di Ammonium Phosphate (DAP) samples procured from different regions of India during 2021-2022. The samples were analysed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), for which the quantification limit was 3 μg.L-1. The reliability of the method was checked against laser fluorimetry and X-ray fluorescence analysis. The method was further validated through spiking studies. Uranium concentrations in the 2021-2022 sample collection were in the range of 8-360 mg [U].kg-1 P2O5. The average uranium content was estimated to be 204.2 mg [U].kg-1 P2O5, with standard deviation of 105.7 mg, which was comparable to the average of 243 mg [U].kg-1 P2O5 reported f.. View More»
