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...
