| Abstract: | A new spectrophotometric method for the microdetermination of uranium(VI) from phosphorites in the presence of commonly occurring metal ions has been developed. Uranium is extracted from chloroform solution of N-phenyl-2-naphtho-hydroxamic acid (N-P-2-NHA) at pH 4.0–4.5. The orange-red extract has the maximum absorption at 515 nm. The extraction was quantitative and obeys Beer's law at 515 nm. |
