REMOVAL OF ORGANIC HALOGENS FROM INORGANIC CHLORIDES BY ACTIVATED CHARCOAL IN AIR SAMPLES

Determination of inorganic chloride from stationary sources in the presence of organic chloride compounds is of great importance during the analysis. The amount of released inorganic chloride into atmosphere was determined with burned refuse-derived fuel (RDF) originated plastic wastes according to the rule of Hazardous Waste Regulations. Organic chlorides absorbed in scrubber solution during the sampling time interfere for analysis of inorganic chloride by ion chromatography. Organic chlorides are removed by using two different activated charcoal tubes so that inorganic chloride analysis is provided more reliably. Recovery of inorganic chloride levels in the scrubber solution was obtained approximately 50% by using granular activated charcoal where these levels increased by approximately 95% when it is passed from the powdered activated charcoal. The amounts of chlorides were obtained 0.13, 0.50, 0.91 mg Cl-/Nm(3) using 0%, 8%, 12% and 15% RDF ratio after Di.Elle activated charcoal and 0.13, 0.63, 0.93, 1.13 mg Cl-/Nm(3) using 0%, 8%, 12% and 15% RDF ratio after Merck activated charcoal. Results show that powdered activated charcoal is more effective than granular activated charcoal.
