| Abstract: | The melting sample, their complex action condition and elimination of coexisting interfering ions of barite were studied and barium in the barite was fast and indirectly determined by precipitation and complexometry. The method is fast with precise result, and the recovery is 98. 5% - 100. 7% and RSD is < 2.48% . |
