FURFURALDEHYDE DETECTOR AND METHOD OF MANUFACTURING THE SAME
摘要
Sensing the presence of furfuraldehyde (FFA) in oil is effected by a porous solid sensor (10) comprising aniline acetate entrapped in an inert matrix. The matrix may be a sol-gel preferably based on methyltrimethoxysilane. The solid sensor (10) reacts with FFA to form a pink coloured complex which has a characteristic which correlates with the concentration of FFA in the oil and which can be measured photo-optically. Photo-optical measurement may be by absorption or fluorescence when the sensor is irradiated with an interrogating beam. The absorption maximum wavelength is about 525nm and irradiation at that wavelength produces a maximum fluorescent output at about 570nm.
