| 摘 要： | 用甲苯萃取废水中的剧毒物元素磷 ,再用溴水将其氧化 ,在稀硫酸 (或硝酸 )介质中 ,磷 铋 钼三元络合物可被抗坏血酸还原生成磷铋钼蓝 ,在 70 0nm处进行光度测定。此法比一般钼蓝法灵敏度高 ,干扰元素少 ,常温下即可迅速充分显色 ,对工业废水中元素磷的测定快速准确 |
| 关 键 词： | 磷铋钼蓝 剧毒物元素磷 甲苯 |

| Abstract: | In waste water,highly toxic phosphours can be extracted by toluene,then bromine water can be used to oxidize it; and in diluted sulfuric acid,phosphorus bismuth molybdenum complex can be reduced to phosphorus bismuth molybdenuim blue.we can determine the complex by photometry under 700 nm.This method has higher sensitivity and less interference than normal molybdenum blue photometry.The method is very useful in determination of phosphorus in industrial waste water. |
| Keywords: | phosphorus bismuth molybdenum blue highly toxic phosphorus and toluene |
