Determination of Micro Amounts of Ga in Rocks by Chromato-graphic separatton withr P350 |
| |
| Abstract: | A new extraction chromatographic technique for rapid separation of Ga in
rocks using dimethylheptyl methylphosphonate (P350) as stationary phase and
polydivinylbenzene (x-5) resin as supporter has been studied.
The sample solution in 2.0 N HCL-3.4 N NaCl medium was introduced on
the chromatographic column,Ga can be eluted quantitatively by water.The
percentage recovery of Ga was 99.5-100.1%·This method is applicable to
determination of O.OOOOx-0.Ox0o gallium in rocks. |
