title: ATOMIC-ABSORPTION AND ATOMIC-EMISSION WITH INDUCTIVE CONNECTED PLASMA DETERMINATION OF IRON AND MANGANESE IN CURATIVE CLAYS.
abstract: Manganese in curative clays was carried out. It was shown that maximum of analytical signal is getting at using triton -100 ( = 4 %) and ultrasound treatment of the analyzed solutions during 20 minutes. By variation of the sample it was established, that systematic error is ambiguous. An accuracy of the results of analysis was checked by the method "injected-found out". Coherence of the results, obtained by two independent methods was estimated by F-and t-criteria. It was proved that run of the
