【Abstract】 Based on the theory of iodimetry,a new analytical method for the rapid titration of manganese dioxide in pyrolusite is developed.Under the optimized conditions,the determination results of the method are in good agreement with recommended values,the relative standard deviation is less than 0.15%. The method is simple, rapid, accurate and reliable. It can be used for the determination of manganese dioxide in pyrolusite.更多还原
