QCMを用いた燃焼由来の疎水性PMのリアルタイム分離測定

抄録

Combustion origin particulate matter (PM) has different characteristics such as hydrophilicity and hydrophobicity depending on the combustion method, however it is difficult to separate each PM characteristics. In this study, to develop real-time selective PM sensing system using a quartz crystal microbalance (QCM), PM adsorption characteristics on the QCM surface was investigated. PM emitted from a pool flame of hydrocarbon fuel such as cyclohexane and toluene was supplied to the QCM, and the frequency shift of the QCM was measured. In addition, polystyrene coated QCM with hydrophobic and acetylcellulose coated QCM with hydrophilic characteristics were also investigated.
