| 摘 要： | 水中碱度测定采用多种指示剂进行对比测试研究。实验表明，采用酚酞、茜素红-甲基红混和指示剂有良好的测试效果。采用酚酞、甲基橙有较好的测试效果；采用百里酚蓝-甲酚红、溴甲酚绿-甲基红混和指示剂的测试效果较差。提出采用酚酞、茜素红-甲基红混合指示剂作为水中碱度测定的新指示剂。

| Abstract: | Varied indicators were applied for the determination of water alkality. The results showed that the mixed indicator of phenolphthalein with alizarin red-methyl red had the best effect, the phenolphthalein and methyl orange followed, the mixed indicator of thymol blue-cresol red with bromocresol green-methyl red was bad. So the mixed indicator of phenolphthalein with alizarin red-methyl red could be used as the new indicator for the alkalify water determination. |
