Description 733-742
The increasing presence of toxic gases, particularly acetone, poses significant threats to both the environment and human
health. Effective detection of acetone is crucial, necessitating the development of reliable and sensitive sensors. This study
explores the use of Nano NaA zeolite as a promising material for acetone sensing, leveraging its excellent adsorption and
desorption properties. Comprehensive material characterization is performed using X-ray Diffraction (XRD), Fourier
Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis-Differential Thermal Analysis (TG-DTA), Scanning
Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDAX) and Atomic Force Microscopy (AFM). The
sensing characteristics of Nano NaA zeolite are rigorously evaluated. The sensor exhibits optimal performance at an
operating temperature of 75 °C, with a response time of 88 seconds and a recovery time of 75 seconds. The sensor
demonstrates excellent sensitivity at a saturation concentration of 85 ppm. Repeatability tests conducted over three trials
confirmes the sensor’s consistent performance, while durability assessments conducted over a 30-day period (with
measurements after every 5 days) highlights its long-term stability. Additionally, the study investigates the effect of acetone
exposure on optical and dielectric properties of the sensor. This research underscores the potential of Nano NaA zeolite as
an effective acetone sensor, offering valuable insights into its optical and dielectric properties. The findings support the
development of robust and durable acetone sensors for environmental monitoring and human safety.
