| 中文摘要 |
| 矿物油(原油、机油、柴油等)、苯胺、部分金属离子及ClO-等物质对4-AAP法测定污水中的挥发酚有干扰。本文采用标加干扰物的方法研究了各种干扰物质对挥发酚测定过程中的回收率的影响规律,得到总回收率Y方程。由Y值和4-AAP法测定值CD可求得水样中挥发酚的实际含量CT(CD/Y)。混和干扰物加标拟合实验结果的相对误差<±5%。该方法测定实际水样的结果与4阶导数光谱法的结果基本吻合。本文是针对油矿区污水特点,提出的消除各种干扰挥发酚测定物质影响的研究方法。 |
| 英文摘要 |
| he interference patterns with different mineral oils (crude oil,machine oil and diesel oil),aniline,some metal ions and ClO-,etc. in the 4-AAP photometric determination of volatile phenols were studied. The recovery of phenols in the presence of different amounts of interference substances was determined spearately Then,the total recovery equation Y was established. The true concentration CT of volatile phenols in wastewaterwas determined with the value CD found by 4-AAP method and the equation Y. The result from standard addition experiment with mixed interference substances shows that its relative error to the calculated value by the equation Y is below 5%. The determined result of wastewater sampleis coincident with the results determined by the derivative photometric method. This method canbe used for the determination of volatile phenols in oil field wastewater. |
