| Abstract: | An atomic absorption spectrometry for the determination of sulphur in the ironore and zinc concentrates without any prior separation is described. The method is based on the replacement reaction of chromate ion in the barium chrornate with . The sulphur is determined indirectly with the determination of chromate replaced by FAAS. The method is simple, rapid and accurate. |
