| Abstract: | This study determined pH value of domestic drinking water by standard buffer colorimetric method of GB/T 5750-2006.Combining with the extant experience,improved the method on preparation of indicator and other important processes.Tap water,river water,well water and mineral water were determined by both standard buffer solution colorimetric method and glass electrode method.The relative standard deviations were between 0.2 ～ 1.3%.The results obtained were satisfactory. |
