本文作者用一种新的特殊试剂,来鉴别磷、间,对一苯二胺,并改进行为定量测定。试验可以在试管,点滴盘,滤纸上进行。试管法:放5ml胺液(浓度为10~(-1)—10~(-4)M)于试管中,加1滴磷钼酸溶液(15g磷钼酸溶解在90ml蒸馏水中),在同样操作下进行一空白试验,2小时后观察颜色变化。点滴盘法;取5滴胺溶液在点滴盘上,加1滴磷钼酸溶液,不同的颜色立刻出现,可稳定数小时。
The authors used a new special reagent to identify phosphorus, m-phenylenediamine, and improve behavioral quantitative determination. Test can be in vitro, drip plate, filter paper. Tube method: Put 5ml amine solution (concentration of 10 ~ (-1) -10 ~ (-4) M) in a test tube, add a drop of phosphomolybdic acid solution (15g phosphomolybdic acid dissolved in 90ml of distilled water) Under the operation of a blank test, 2 hours after the observation of color change. Drip plate method; take 5 drops of amine solution in the drip plate, add a drop of phosphomolybdic acid solution, different colors immediately appear, can be stable for hours.
