Abstract
A spectrophotometric method has been developed to determine thorium using 3-hydroxy-2-(2'-thienyl)-4H-chromen-4-one (HTC) which forms a 1:4 yellow complex in dilute acetic acid solution with λ m a x at 430 nm. The method is free from the interference of a large number of metal ions of interest. Molar absorptivity and Sandell's sensitivity of the complex are 3.95×10 4 L mol - 1 cm - 1 and 0.0059 μg cm - 2 , respectively.
