A sensitive and selective method for the extraction and microgram determination of niobium(V) with N-p-chlorophenyl-␣-phenylstyrylacrylohydroxamic acid (PCPPSAHA) is described. The niobium-PCPPSAHA complex has a max of 385 nm and a molar absorptivity of 3.7 Γ— 10 4 l mol -1 cm -1 . The system obeys B
