Abstract

AS THE FREQUENCY OF ACOUSTIC WAVES (AW) IS CONSIDERED AS A FINGERPRINT PROBE FOR SELECTIVE DETECTION AND DETERMINATION OF GAS SPECIES [1-3], THEREFORE IN THIS STUDY, A NOVEL TECHNIQUE IS INTRODUCED BASED ON ACOUSTIC WAVE OF THE PYROLYSIS OF ELECTROACTIVE SPECIES INSIDE FLAME AS FINGERPRINT DETECTION SYSTEM FOR SELECTIVE DETERMINATION OF GAS POLLUTANTS BY ALTERNATIVE CURRENT (AC) AMPEROMETRY. STRAIGHT CORRELATION IS EXISTED BETWEEN BURNING FREQUENCY OF POLLUTANTS AND THAT APPLIED TO AN ELECTROCHEMICAL CELL FOR SELECTIVE DETECTION AND DETERMINATION. TO CLAIM THIS PHENOMENON, CARBON MONOXIDE (CO) IS SELECTED AS DETECTION SYSTEM. BURNING FREQUENCY OF CO INSIDE A H2/AIR FLAME IS EVALUATED IN AN ISOLATED SYSTEM USING A MICROPHONE AND THE SOUND CARD OF A COMPUTER THROUGH SOFTWARE. SOUND FREQUENCIES ARE THEN CONVERTED INTO AC ELECTRONIC SIGNALS (WAVEFORM) USING A PROGRAMMABLE FUNCTION GENERATOR. SIGNIFICANT ANODIC CURRENT IS EVALUATED FOR THE OXIDATION OF CO ON THE SURFACE OF GLASSY CARBON ELECTRODE IN THE PRESENCE OF FOREIGN GASES SUCH AS O2, CO2, H2S, C2H2, H2 AND ALSO VAPORS OF ACETONE AND ALCOHOLS. THIS TECHNIQUE CAN BE CONSIDERED AS A SELECTIVE AND SENSITIVE DETECTION SYSTEM FOR CO DETECTION AT PARTS PER MILLION (PPM) LEVELS. LINEAR RANGE IS BETWEEN 35-100 PPM. DETECTION LIMIT FOR CO DETECTION IS ALSO EVALUATED TO ~18 PPM WITH RESPONSE TIME EQUAL TO ~12S. REPRODUCIBILITY FOR ABOUT FOUR REPLICATE ANALYSES OF CO IS EVALUATED TO 3.09%. THE RELIABILITY OF THIS METHOD IS FINALLY EVALUATED VIA DETERMINATION OF CO IN TWO DIFFERENT INDUSTRIAL GAS SAMPLES.
