| 摘 要： | 甲醛在室内环境污染控制标准中限量最低,而规定的检测方法中只有酚试剂光度法的检出限低,能判别Ⅰ类工程的测量值是否超标。本文对国家标准中的乙酰丙酮光度法的测定条件,如显色温度、时间、比色皿长度等作了改进,使方法的检出限降至0.008 mg/m3。本法经6个有资质的实验室验证,结果准确、重现性好、分析成本低。 |

| Abstract: | The limit of formaldehyde is lowest in the standard for indoor environment pollution control, only hydroxybenzene reagent spectrophotometric method has the ability of judging whether the detection value of kind I project is beyond the concentration limit due to its lowest detection limit. In this work, we propose an improved normative acetylacetone spectrophotometric method in which the determination parameters such as temperature, time and length of utensil were modified and the detection limit was 0. 008 mg/m^3. The improved method has the characteristics of accuracy, repeatability and low cost. |
