| Abstract | ||
| The reactions of 5[2.3-dihydro –1.4-phthalazindionazo] 8-hydroxyquinolin with Sc,Y and La ions have shown that 1:1and 1:2 complexes were formed in solution. The complexes were found to be suitable reagents for direct spectrophotometric microdetermination of scandium. Yterium and Lanthanium, the stepwise stability constants were evaluated applying corresponding solution method. | ||
