摘要
Sorption of Tb3+, ions by zirconium phosphate (ZrP), their complexation with some pyrazolones-5, and composition of compounds formed on a solid matrix are studied. Unlike solutions with the ratio Tb : pyrazolone = 1 : 3. compounds formed on ZrP have the ratio Tb : L = 1 : 3, 1 : 2, and 1 : 1, depending on the availability and size of a substituent at the reaction site. The luminescence intensity of the adsorbed Tb pyrazolonates as found to correlate with a sum of the Hammer induction sigma-constants of substituents in the ligand molecule. The luminescence intensity of the studied complexes on ZrP is two times and more hi.-her than that in solutions, which makes it possible to use ZrP as a solid substrate.
