| Abstract: | The conditions for synthesis of alizarin red-S chelate resin and for seperation and preconcentration of Rh and Ir in geological sample have been investigated.Experiments show that Rh and Ir in solution are enriched on alizarin red-S chelate resin column in pH?2.0 HCl and are eluted with 3?% acidic thiourea.The recoveries of them are 99.2?% and 98.3?% respectively.The results obtained are in agreement with the recommended values of standard reference material. |
