Datection of Carboxylic Acid Vapours Using Piezoelectric Crystals with Crown Ether Coatings
摘要:
This work describes three crown ether-coated piezoelectric crystal sensors for detection of carboxylic acid vapours.All three have excellent reproducibility and stability (lasting for at least 100 days).Two of them show good sensitivity (137-1500Hz/mg/L) and high selectivity.Cis-diamino-dibenzo-18-crown-6 can be used as the coating material for the detection of formic acid.The effect of crown ethers structure on the detection sensitivity and selectivity for acid vapours was discussed.
