Abstract A simple, rapid, cost-effective, accurate and precise differential laser-induced fluorimetric method for the direct determination of uranium in mineralised rocks at the percentage level is presented, based on the comparison of the fluorescence of the standard with a sample of similar but unknown concentration on the same sample weight basis, by the use of H 3 PO 4 –NH 4 H 2 PO 4 as a fluorescence enhancing reagent. The relative standard deviation of the method was 0.3–0.5% ( n =9) for… Expand
