传感技术用于甲醛测定的研究

甲醛是一种重要的工业原料,在化工、食品、建材等方面有着广泛的应用。由于甲醛毒性大,且被怀疑具有致癌作用,目前已被认为是工厂区和室内空气中最重要的污染物之一。随着人们对空气污染的日益关注,对甲醛的准确及时检测显得更加重要。基于传感器技术而研制出的甲醛测定仪,让我们看到传感技术运用于甲醛测定领域的发展前景。本文就测定甲醛的传感器技术如电化学传感器、光化学传感器、金属氧化物传感器、电子鼻以及声表面波式传感器的一些重要应用进行了阐述。

Sensing Technology for the Determination of Formaldehyde

Formaldehyde is an important industrial raw material. It has been used extensively in chemical, food and btfilding materials. Owing to its high toxicity and possible carcinogenic properties, formaldehyde is now recognized as one of the most important pollutants in beth workplace and ambient atmosphere. Along with people＇s increasing attentions on air pollutions, accurate and rapid method for the determination of formaldehyde is even more important. Formaldehyde analyzer based on sensor technology, let us aware of the prospects in the field of sensor technology, used in formaldehyde determination. This paper is described on the some of important applications of the sensor technology such as electrochemical sensors, luminescence sensors, metal oxide sensors, electronic noses and surface acoustic wave sensors in the determination of formaldehyde.
