Development of a needle trap device packed with titanium‐based metal‐organic framework sorbent for extraction of phenolic derivatives in air

Abstract

We developed a novel method of needle trap device packed with titanium‐based metal‐organic framework for the extraction of phenolic derivatives in air followed by gas chromatography‐flame ionization detector analysis. The synthetized adsorbent was packed inside a 22‐gauge spinal needle. This method was first tested at laboratory scale, and then was used for field sampling of phenolic derivatives in air. A glass chamber placed on a heater at 60°C was used to provide different concentrations of phenolic derivatives. The desorption conditions and breakthrough volume were optimized using response surface methodology. The limit of detection and limit of quantitation of the proposed method were estimated to be in the range of 0.001–0.12 and 0.003–0.62 ng/mL, respectively, indicating a high sensitivity for the suggested sampler. Storing the packed needle trap device in a refrigerator at 4˚C for 60 days did not dramatically affect the storage stability. Our findings indicated that there was a high correlation coefficient (R2 = 0.99) between the measurement results of this method and the NIOSH recommended method (XAD‐7 sorbent tube). Therefore, it can be concluded that the needle trap device packed with titanium‐based metal‐organic framework can be used as a efficient method for extraction of phenolic derivatives in air.

“…Cooperative gaminal and vinylogous ABO has been reviewed (Figure 1, Parts II and III). 30,31 Behind the chemical studies, many efforts have been done to access a mild and green condition for the electrosynthesis and application of MOFs [39][40][41][42][43][44][45][46][47][48][49][50] . Anodic and cathodic electrosynthesis methods are the important techniques that recently have been used for the preparation of various kinds of MOFs [39][40][41][42][43][44] .…”

“…The needle trap device (NTD) as one of the micro-extraction techniques can be employed in the active sampling, preparation, and desorption of workplace air pollutants in aqueous and gaseous matrices in one step and without consuming organic solvents. 12 Moreover, the increased absorption capacity and resolving the needle fragility issue are advantages of the suitable design of adsorbent placement inside the needle. 13,14 One of the key points of NTD is its exibility in the employed adsorbent.…”

“…Various adsorbents with interesting properties have been used in the NTD method. 12,[15][16][17] One of the best candidates for needle packing is the metal-organic framework (MOF) material. The footprint of MOFs can be seen in chemical applications such as separation, storage, catalysis, drug delivery, pollution analysis, and electrochemical applications such as supercapacitors, electrocatalysis, and sensors.…”

“…Many studies have investigated the effect of commercial and synthetic adsorbents in NTD for detecting various chemicals. [10][11][12] The MOFs are new porous structures that its principal was introduced in the early 1990s by Rabson and Hoskins. 13 These frameworks have an organic-mineral hybrid nature that has the properties of both organic and inorganic elements.…”
