When conducting permanganate index analysis in high-altitude areas,the results of permanganate index measurement are often low or even distorted due to the objective factors of high altitude.This study takes the water bath digestion time and analysis formula in the standard method"GB11892-89 Determination of Permanganate Index"as the starting point.By adjusting the water bath digestion time and optimizing the analysis formula,conduct experiments using an automatic permanganate index analyzer,the goal is to accurately determine the permanganate index in high-altitude areas and improve the accuracy of permanganate index measurement.
