Zeolite‐based cataluminescence sensor for the selective detection of acetaldehyde

et al. 2007

The reactions of acetaldehyde with O atoms in the cages of large-pore zeolites have been discovered to result in light emission. The luminescence characteristics of acetaldehyde vapours passing through the surface of chosen zeolites were studied using a cataluminescence-based detection system. To demonstrate the feasibility of the method, the detection of acetaldehyde using catalysts was studied systematically and a linear response of 0.06-31.2 microg/mL acetaldehyde vapour was obtained. Methanol, ethanol, isopropanol, methylbenzene, chloroform, dichlormethane and acetonitrile did not interfere with the determination of acetaldehyde. Acetaldehyde vapour could also be distinguished from some homologous series such as formaldehyde, cinnamaldehyde, glutaraldehyde and benzaldehyde on this catalyst, possibly due to the stereoselectivity of the zeolite and its specific reaction mechanism. Moreover, acetaldehyde was quantified without detectable interference from formaldehyde in four artificial samples. Thus, this kind of cataluminescence-based sensor could be potentially extended to the analysis of volatile organic compounds in air, and the simple and portable properties of cataluminescence-based sensors could also make them beneficial in many areas of analytical science.

A method of two-step gradient capillary electrochromatography (CEC) was developed to measure 12 carbonyls (aldehydes and ketones) in indoor air samples. The carbonyls were derivatized with 2,4-dinitrophenylhydrazine (DNPH) and then separated by a two-step gradient CEC on a C8 column. Effects of various instrumental conditions on the separation, including buffer concentration, organic modifiers, voltage, and cassette temperature, were investigated. The method detection limits for the 12 carbonyls ranged from 0.2 µg to 1.6 µg per sample and the recoveries were generally between 90 and 120%. A subset of 30 indoor air samples containing formaldehyde and acetaldehyde from 75 randomly selected homes in the city of Ottawa, Canada were measured using the CEC method. The concentrations of formaldehyde and acetaldehyde in these indoor air samples ranged from 5.8 µg/m 3 to 85 µg/m 3 , and from 4.4 µg/m 3 to 38 µg/m 3 , respectively. The comparison between CEC and the traditional HPLC method shows a good agreement in measured values.
