水样中挥发酚的测定方法有对4-氨基安替比林-氯仿萃取分光光度法(以下简称“4—AAP法”)和直接比色法[1]。4—AAP法具有稳定性好,灵敏度高等优点,但操作烦琐,影响因素较多,实验条件不容易控制。直接比色法是针对挥发酚浓度较高的条件。我们将这两种方法合并,对其中一些检测条件 Determination of volatile phenol in water samples for 4-aminoantipyrine - chloroform extraction spectrophotometry (hereinafter referred to as “4-AAP method”) and direct colorimetry [1]. The 4-AAP method has the advantages of good stability and high sensitivity, but the operation is cumbersome, the influencing factors are more, and the experimental conditions are not easy to control. Direct colorimetric method is for the higher concentration of volatile phenol conditions. We combine these two methods for some of these test conditions
