| Abstract: | new method for simultaneous determination of Co Mn and Br in plant sample by X - ray fluorescene spectrometer was studied. Optimum experiment conditions, factors interfering experiments accuracy and precision of the method were investigated. Recovery rates of the three elements were as followed: Co 95.3%-103.0%, Mn 96.0%-104.0%, and Br 94.8%-105.0%. The proposed method has been satisfactorily applied to analysis of Co,Mn,Br in samples from purified terephthalic acid plant. |
