The heteroligand complex of zirconium with benzidine-bis-azopyrocatechol and cetylpyridine have been investigated by the spectrophotometric method. The condition of complexing, composition, physico-chemical and analytical characteristics of the complex have been determined. The photometric determination method of zirconium has been worked out and the influence of strange ions on the determination of zirconium(II) has been studied.
