| 中文摘要: |
| 新型显色剂2-对氨基苯基-2′-羟基二乙胺与水中挥发酚在碱性条件下，经铁氰化钾作用发生反应，反应产物用乙酸丁酯萃取后在可见紫外分光光度计600 nm波长下比色定量。该方法测定挥发酚在0.001 mg/L～0.100 mg/L范围内线性良好，方法检出限为0.000 8 mg/L，加标回收率为100%。用该方法与4-氨基安替吡啉三氯甲烷萃取分光光度法同时测定实际水样，结果无显著差异。 |
| 英文摘要: |
| In alkaline condiction, by means of potassium ferricyanide, volatile phenol reacted with 2 p aminophenyl 2′ hydroxyl diethylamine, a new chromogenic agent, the reaction product was extracted by butyl acetate and determined at 600 nm wavelength by ultraviolet spectrophotometer. The method had good linearity when volatile phenol was in the range of 0.001 mg/L to 0.100 mg/L. The detection limit was 0.000 8 mg/L, the spiked recovery was 100%. 〖JP2〗There was no significant difference between this method and the 4 AAP spectrophotometric method according to the results of actual water samples determined by the two methods. |
