Abstract
Abstract The spectral characteristics and analytical properties of 4, 4′-Biazobenzenediazoaminobenzene as a new chromogenic reagent have been described and the optimum conditions for reaction with eight metal ions are presented. In the presence of Triton X-100 and sodium tetraborate solution, the reagent can be used for the determination of Hg, Ni, Cd. The molar absorptivities are 1.8×105 l.mol−1. cm−1 at 515 nm for mercury, 2.0×105 l.mol−1. cm−1 at 540 nm for nickel, and 1.8×105 l.mol−1.cm−1 at 526 nm for cadmium. The recommended procedure has been used for the spectrophotometric determination of cadmium in waste water.
