| Abstract: | For continuosly determining trace amount of diversified elements,a sensitive and selective method is developed by combining floatation technique with that of atomic collection and flame atomic absorption spectrometry(FAAS ). The ionic associate, M-I-RB, M-SCN-MV or M-SCN-CV, is floated with toluene and dissolved in dimethyl-formamide and then determined by atomic collection and FAAS. The authors investigate the behaviour of floating metallic ion and the performance of its analysis land go further into the operating condition of atomic collection and FAAS. The method has been applied to the determination of gold in geological samples,with the result coinciding with standard value. |
