Quantitative analysis of Nd, U, or Pd in 3 mol dm $^{-3}$ (M) HNO $_{3}$ was performed by reflection absorption spectrophotometry at ultraviolet-visible-near-infrared (UV/Vis/NIR) region. A sample chamber with optics for reflection measurement was designed and attached to a UV/Vis/NIR spectrophotometer by optical fibers. The reflection absorbance showed linear relations with concentrations of Nd, U, and Pd at the absorbance region less than 0.1. The quantitative analysis was found to be possible for 3 M HNO $_{3}$ solutions containing [Nd] ca. 0.2 M, [U] ca. 0.04 M, or [Pd] ca. 0.01 M at maximum.
