Abstract
A spectrophotometric method was developed for determining simultaneously present Np, Am, and Pu in sulfuric and perchloric acid solutions. The molar extinction coefficients ε were determined. In the concentration ranges 1.0 × 10−4−2.0 × 10−3 M for Pu and Am and 5.0 × 10−4−1.0 × 10−2 M for Np, the overall error does not exceed 5%. The detection limits are 3.0 × 10−5 M for Pu and Am and 1.0 × 10−4 M for Np.
