水样中挥发酚测定的边界条件探讨

在环境水质监测中，水中挥发酚的测定是最重要的有机监测项目。水样测定中首选测定方法是4-氨基安替比林光度法。在水样预处理和分析操作过程中，既要严格执行操作技术规程，更要充分考虑分析过程中的关键技术、边界条件等一些因素的影响，特别要考虑4-氨基安替比林的空白值、显色剂的稳定性、pH值的影响及缓冲液的使用等以保证实验的顺利进行和分析数据真实准确有效。

Study on Boundary Condition of Determing Volatile Hydroxybenzene in Water

In the area of monitoring water quality, the most important organic items are volatile hydroxybenzene, and 4 - aminoantipyrine photometric method is the first choice for determining volatile hydroxybenzene in water. In the process of preconditioning water samples and analyzing, we not only strictly execute the technical specification of operation, but also fully consider some factors such as the key technology, boundary condition et al. Moreover, we should especially take account of blank value of 4 - aminoantipyrine, stability of chromogenic reagent, pH and buffer solution and so on. To do this, successful experiment can be guaranteed and accurate and effective data can be achieved.
