A New Spectrophotometric Method for Thorium Determination Using 1,4-Dihydroxyanthraquinone

A new reagent, 1,4-dihydroxyanthraquinone ( 1,4-DHA ), is described for the spectrophotometric determination of thorium(IV). Optimization of the formed thorium−1,4-DHA complex was performed by studying several parameters such as methanol concentration, suitable pH, dye concentration, temporal stabil...
