based on the reaction
of diperiodatoargentate(III) (DPA) with uric acid in alkaline medium to emit CL. With the peak height
as a quantitative parameter applying optimum working conditions, the relative CL intensity was linear
with the uric acid concentration in the range of 4.0×10−7–2.0×10−4 mol L−1 with a detection limit of
1.2×10−7 mol L−1 (3).
