Study on Spectrophotometric Determination of Uranium in Ore and Commercial Samples

Acetophenone 2′, 4′- dihydroxy semicarbazone [A24DHS], a novel analytical reagent, is proposed as a spectrophotometric reagent for U (VI). NMR, IR, and elemental analysis are used to characterise the reagent A24DHS, which is synthesised in the lab. In an acidic aqueous solution (pH = 7.4), a spectrophotometric method is presented for the trace determination of U(VI) using A24DHS as a spectrophotometric reagent ((lambda)max = 340 nm). In the concentration range of 1 to 10 ppm, Beer’s law is followed. The A24DHS creates a coloured complex with a ratio of 1:2. With a molar absorptivity of 2896.43 L mol-1 cm-1, Sandell’s Sensitivity is 0.0823 (mu)g cm-2. The proposed method has been used to determine Uranium in ores and commercial samples with great success. The precision and accuracy obtained were adequate for use in the industry in question. This chapter details the method development for determination of Uranium in different commercial samples.
