| 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 λmax at 430 nm. The method is free from the interference of a large number of metal ions of interest. Molar absorpti vity and Sandell's sensitivity of the complex are 3.95×104 L mol-1 cm-1 and 0.0059 μg cm-2 respectively. |
