Air Quality Monitoring: Co, Co2, H2s Gases

Arduair: Air Quality Monitoring

Air pollution and quality monitoring is extremely important in today’s world as it has a direct impact on human health. Air pollution is on the rise due to a number of anthropogenic activities and its monitoring is of vital importance to mitigate certain measures to control it. In this paper we put forward a low-cost and low-power sensor based system for air quality monitoring. This sensor base...

Monitoring the Quality of Air

Biotreatment of H2S- and NH3-containing waste gases by co-immobilized cells biofilter.

Gas mixture of H2S and NH3 in this study has been the focus in the research area concerning gases generated from the animal husbandry and the anaerobic wastewater lagoons used for their treatment. A specific microflora (mixture of Thiobacillus thioparus CH11 for H2S and Nitrosomonas europaea for NH3) was immobilized with Ca-alginate and packed inside a glass column to decompose H2S and NH3. The...

Performance of a CO2 Impedimetric Sensor Prototype for Air Quality Monitoring

Carbon dioxide detection is a relevant issue in many fields, and this work focuses on the use of a BaTiO(3)-CuO sputtered thin film layer in a gas sensor prototype for air quality measurements. For this, a double side sensor was fabricated, with a Pt heater on one side and the sensing layer over the electrodes on the other side. The uniformity of the temperature on the sensing layer was tested ...

EIS investigation of CO2/H2S corrosion

This paper covers one of the building blocks required to complete a mechanistic CO2 / H2S corrosion model: electrochemistry of carbon steel CO2 corrosion in the presence of traces of H2S (3-250 ppm in the gas phase). Electrochemical impedance spectroscopy and linear polarisation resistance were used to investigate the mechanism of CO2/H2S corrosion in a glass cell at room temperature, at atmosp...
