酚试剂分光光度法测定空气中甲醛的试验分析

Experimental Analysis of Phenol Reagent Spectrophotometric Determination of Formaldehyde in Air

当前,在新装修的建筑房间内含有较高的甲醛,人们如果长期活动在房间中,就会吸引大量的甲醛而引发身体上的疾病。因此,在我国环境监测工作当中,通过开展空气中甲醛的试验,加强甲醛的预防与控制具有重要的意义。结合有关工作实践,通过对酚试剂分光光度法进行空气中甲醛的测定,利用显色温度、时间、剂用量对甲醛浓度的影响进行了深入的探讨,通过试验结果分析,其结果稳定,满足最佳试验条件要求。

At present,the newly-renovated building room contains high formaldehyde.If people are active in the room for a long time,they will attract a lot of formaldehyde and cause physical diseases.Therefore,in China’s environmental monitoring work,it is of great significance to strengthen the prevention and control of formaldehyde by carrying out tests of formaldehyde in the air.The article combined with relevant work practices,through the phenol reagent spectrophotometric method for the determination of formaldehyde in the air,the use of color temperature,time,and the amount of agent to affect the concentration of formaldehyde,through the analysis of test results,the results are very stable,meet the requirements of the best test conditions.
