- Determination of carbon monoxide using a coated quartz crystal sensor O. M. Guimarães M. E. D. Zaniquell J. R. M. Castro V. R. Balbo J. F. Andrade Química quartz crystal carbon monoxide piezoelectric sensor phthalocyanine nickel(II) Carbon monoxide was detected and determined by a piezoelectric quartz crystal sensorcoated with nickel(II)-phthalocyanine 50 % (v/v) solution in glycerine. Studies on the effect oftemperature, flow rate, and some possible interferents were carried out. Calibration curves, sensorstability (lifetime) and the precision of measurements were also verified. The resulting selectivity isprobably due to the coordinative binding between the electronically unsatured metal complexes and theanalyte. The analytical curve is linear in the concentration range 0.10 to 1.0 % (v/v). 2006 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42931403 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.4 Vol.31
