Development of a Needle Trap Device Packed with HKUST-1 Sorbent for Sampling and Analysis of BTEX in Air

In this study, we developed a needle trap device packed with HKUST-1 (Cu-based metal-organic framework) for the sampling and analysis of benzene, toluene, ethylbenzene, and xylene (BTEX) in ambient air for the first time. The HKUST-1 was synthesized via the electrochemical process. Afterwards, the adsorbent was packed into 22 gauge needles. To provide the different concentrations of BTEX, the syringe pump was connected to the glass chamber to inject a specific rate of the BTEX compounds.

The article shows the importance of ensuring that the air of small-size rooms at private production facilities where equipment is arranged densely has specified parameters. Theoretical grounds of ventilation performance evaluation are considered. It is pointed out that a power saving air distributor ensuring a prompt cease of the airflow has not been developed yet. The advisability of air delivery to the room’s working area is stressed. The using of low-speed panel-section air distributors in a private production facility room is considered.
