| 摘 要： | 用碘量法测定了污水中的硫化物,实验探讨了加药次序、空白滤纸、滴定终点的判断问题。由实验结果可知:必须严格按照先加入碘标准溶液、再加入硫酸溶液的次序进行处理。空白实验中是否使用滤纸,其结果差异显著。在反应过程中,随着放置时间延长,硫化物测量值会增大。

| Abstract: | The Iodine amount method was used to determine sulfide in wastewater. Several details in experiment were discussed. The adding order of medicine, usage of blank filter paper and judgement of terminal point were investigated experimentally. The iodine solution is necessary firstly to be added into wastewater and then adding sulfide solution in the experiment. The blank filter paper and staying time of sulfide solution have important effects on experiment. |
