Abstract:In the determination of permanganate index in underground water by acid method, the results show that direct heating method has advantages of saving time and labour, and its precision and degree of accuration can all meet the demand of environmental monitoring standard. It is especially suitable for large number of samples.
Keywords:Permanganate index  heating  time
