摘要
本文依据GB/T 5750-2006标准比色列缓冲溶液比色法测定生活饮用水中的pH值,结合我实验室的检测经验对国标中指示剂的配制等重要环节进行了补充,并采用标准缓冲溶液比色法和玻璃电极法同时对自来水、河水、井水及矿泉水的pH值进行了测定,相对偏差在0.2%～1.3%之间,结果满意。
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.
