Formation of U(VI) and Th(IV) Complexes with Chromotropic Acid in Solution

Physical Chemistry Laboratory, Institute of Science, Bombay-400 032 Manuscript received 25 July 1983, accepted 27 October 1933 MEHROTRA1 et al and other workers2,3 have studied the coordination compounds of chromotropic acid (CT A). This acid provides two hydroxyl groups for coordination and hence it is interesting to study the complex formation. The systems UO2(II)-CTA and Th(IV)-CTA have not been studied so far. We have therefore undertaken the study of these two systems in this investigation
