Theoretical and Experimental Investigation of Carbon Monoxide, Humidity and Temperature Relations in Zonguldak Province of Turkey

Özet

The sensor monitoring of ambient carbon monoxide (CO) which was mainly emitted by the coal mines and power plants was performed in the center of Zonguldak province of Turkey. It was observed that the recorded amount of CO (ppm) highly depended on the amount of humidity (H2O) percent and temperature. The sensor monitored higher CO values at higher temperatures accompanied with lower humidity percent whereas lower CO values at lower temperatures accompanied with higher humidity percent. Consequently, OC…Wn (W: H2O) (n = 1-3) long-range (hydrogen-bonding) interactions were modelled computationally using MP2/6-311++G(d,p) level of theory at selected temperatures. The calculated interaction Gibbs free energies and performed reactivity and stability analyses supported the possibility of carbon monoxide and humidity interactions at lower temperatures with higher humidity percent in parallel with the experimental results. It was concluded that the system presented in this study might be integrated into CO sensor units to improve the sensor response in terms of accuracy and precision.
