| 摘 要： | 4-氨基安替比林(4-AAP)试剂易吸潮结块并受空气氧化,从而使试剂空白值明显增高,必要时可将4-AAP试剂纯化。本文研究了4-AAP试剂空白值对校准曲线斜率的影响,并得出测定挥发性酚时,4-AAP试剂空白吸光度控制在0.045～0.100为最佳。

| Abstract: | 4-AAP (4-Aminoantipyrine) is easy to be slaked and oxided in the air, and it causes an increase of the blank absorptance during determination of phenols with 4-AAP. By purification of 4-AAP the blank absorptance can be decreased. The effect of the blank on the slope of calibration curve was studied. The experimental results showed the suitable blank absorptance of 4-AAP for determination is in the range 0.045 to 0.100. |
