;

The green color of benzene solutions of the chelated complex which pentavalent Pa forms with thenoyltrifluoroacetone in 6M hydrochloric acid is used for a colorimetric determination of pure Pa/sup 231/. The system considered follows Beer's law at 430 and 440 m mu in the concentration range between 1.3 and 8.7 mu g of Pa/sulp 231/ per cm/sup 3/. (tr-auth)
