氯仿提纯4-氨基安替比林方法的验证

Verification of Trichlormethane Purified 4-amino Antipyrine Method

在测定水质的挥发酚实验中,4-氨基安替比林的质量直接影响空白试验的吸光度值和测定结果的精密度,因此有必要对4-氨基安替比林进行一个提纯。

In the determination of the volatile phenol in water, quality of 4- amino antipyrine direct impact absorbency of blank test value and measured results for precision, so it is necessary to purify 4- amino antipyrine.
