研究了四种苯酚降解中间产物——邻苯二酚、对苯二酚、对苯二醌以及顺丁烯二酸对比色法定量检测苯酚浓度的影响，结果表明，对苯二醌中间体对苯酚的定量分析会产生很大的影响，而其它三种物质产生的影响可忽略不计。
The effects of four kinds of phenol degradation intermediates - catechol, hydroquinone, p-benzoquinone and maleic acid on the quantitative determination of phenol were studied. The results showed that p-benzoquinone intermediate reacted with phenol Quantitative analysis will have a great impact, while the other three substances have negligible impact.
