| Abstract: | This method improved the existing determination methods of all kinds of components in powder, which are complicated and verbose, and introduced continuous measurement of multi-elements. Optimal analytical conditions, acidic medium, choosing of concentration, interference of measurement and its eliminating for determination of Potassium, Sodium, Manganese and Iron have been investigated. The results indicated this method is accurate. Recovery of the tested elements is in 95% - 105%. |
