| Abstract: | The research on determining the chlorine of RE oxide quickly had been done. The samples dissolved in nitric acid, the content of the chlorine was determined with colorimetric method of mercuric thiocyanate. Through the experiment of standard addition, standard deviation of chlorine and results' comparing, it was concluded that the accurate and precision of the analytical method used for determining the chlorine of RE oxide quickly can meet the requirements of analytical quality . |
