| Abstract: | Two methods of determining the index of permanganate in water,GB11892-89 and ISO8467-1986,were analyzed here.The former has the features of less brief operation and longer time,the latter has the features of less time and complex operation. Because of their the same reaction principle, the author combined with their advantages and spurned their shortcoming, expounded a method that needs less time and brief operation to meet the need of onerous water quality supervision work. |
