Complex formation in the system zirconium-diantipyrylpropylmethane-acidic dye
Previously, the authors used a metal indicator method to examine the formation of complexes of zirconium with diantipyrylpropylmethane (DAPM) and have shown that two complexes, Zr (DAPM)/sup 4 +/ and Zr (DAPM) /sup 4 +//sub 2/ are formed in 0.1 and 1.0 M HC1, with stability constants of 5.10.10/sup 10/ and 3.80.10/sup 14/ respectively. Now the authors combine this complex with the acidic dye 2-(4-sulfonphenylazo)-1.8-dihydroxynaphthalene-3.6-disulfonic acid (SPADNS). The optimal conditions have been found for the formation of the heteroligand complex. It is shown that Zr (IV) ions are involved in coordination, giving the compound (Zr (DAPM) (HR) 2)/sup 2 -/. A method has been developed for the photometric determination of (0.202.0).10/sup -5/ M solutions of zirconium, and this has been used for the analysis of process water from the Rovensk nuclear power station.
