Ammonium aurintricarboxylate forms a colored chelate complex with tetravalent thorium. The complex, which has maximum absorption in the range 530 to 40 m mu , has been investigated by spectrophotometric and conductance measurements, using job's method of continuous variation, and is found to contain the chelating agent and thorium in the proportion of 1: 1. The structure of the complex has been discussed and it has been suggested that chelation occurs between the quinonoid oxygen and the adjacent carboxylic oxygen. The complex formation constant is 1.10 x 10/sup 5/ and the free energy of formation -6.9 kcal at 25 C. (auth)
