Abstract:
The optimum conditions are studied for fluorimetric determination of hafni- um based on separation with, 743 cation and 717 anion exchange resins. The exitation wave length and the emission wave length are found to be 401 nm and 506 nm respectively. The concentration of Hf obeys Beer slaw in the ra- nge of 0-1 ug/10ml. The recoveries obtained by addition of standard Hf-solu- tion were 98-108 %.
