摘要
对GB/T17657和GB/18580规定的3种方法(萃取法、干燥器法、环境舱法)的影响因素进行了比较,认为应优先采用分光光度法检测甲醛释放量。在检测中要注意环境温湿度、显色及放置时间的掌握、样品平衡放置时间、仪器精度控制等因素。
Comparing influencing factors of extraction, dryer and environmental cabin three methods prescribed by GB/ T17657 and GB/18580, the resnlt was concluded that monitoring formaldehyde emissions should adopt spectrophotometric method. Faeto such as environmental temperature, humidity, colouration and placing time, tile sample balance placing time and instrument accury should be noticed during the monitoring.
