2.107 Uranate
2.107.1 Spectrophotometric method
Kuroda et al. [871] observed that uranium is strongly absorbed from acidified saline
solutions by a strongly basic ion exchange resin in the presence of azide ions. The
distribution coefficient of uranium with 0.5mol L −1 sodium chloride increased rapidly
with an increase in azide concentration, and was much higher than the coefficient
obtained with hydrazoic acid alone. The sorbed uranium was easily eluted with 1mol L −1 ,
hydrochloric acid, and was determined spectrophotometrically. Recoveries of 98.3-
99.6% uranium were obtained from artificial sea water containing 3.4µg L −1 uranium.
