Summary

Selective Photometric Determination of Nickel with Photochemically Generated Anti-2-Furaldehyde 2-Pyridylhydrazone

A sensitive photometric determination of nickel, based on the formation of a coloured chelate with photochemically generatedanti-2-furaldehyde 2-pyridylhydrazone (anti-FAPH), is described. A detection limit of 3 ng/ml, sensitivity of 4 ng/ml and r. s. d. of 0.9% were found. The stoichiometry of the chelate was found to be 3∶1 (L∶M) when thesyn-anti ratio in the photostationary state was taken into consideration. The influence of reaction variables, the effect of foreign ions, and applications of the technique to nickel determination in environmental fume samples and in aluminium-rich materials are described.
