  • A new chromogenic reagent 5-FAsA -DBF was synthesized and its colour reaction with thorium was studied, In a perchloric acid medium of 3.84 mol•L-1, 5-FAsA-DBF reacted with thorium to form a stable coordinate-complex, having its absorption maxima at 630 nm.Its molar absorptivity was found to be 1.63×105 L•mol-1•cm-1 .Beer’s law holds in the concentration range of 0~40 μg of Th(Ⅳ) per 25 mL of solution.The method has been apllied to determinate thorium in seafood with satisfactory results.
