A new analysis method to determine ermanganate index w hich can be used for the fast and automatic on-line monitoring w as established with newly-develo ed a li- ance of the corrosion-resistant constant flow um , low-memory high-effect mixer and currency ool in w hich bubble w as ke t out, and through high tem erature and high ressure and short-time digesting time.
