Abstract

The elution test of chemical substances in active carbon produced from scrap tires with water or organic solvent was performed and was compared with those of reagent active carbon and raw scrap tires. While alkanes (0.076-7.6 mg/kg), alkenes, benzenes (0.047-6.1 mg/kg) and phthalates (0.037-3.2 mg/kg) were detected in the elution test for active carbon produced from scrap tires with acetone, no GC/MS peak was observed in the test with water . On the other hand, alkanes (0.29-10μg/l), alkenes, phthalates (0.91-1.2μg/l), styrene, phenols, bisphenols, ketones, amines, amides, caprolactam, isocyanates, pyridines, quinolines, pyrimidines, imidazoles, triadins, imides, isoindoles, isothiocyanates, benzothiazolone, benzothiazoles, organophosphonic acids and silica compounds were eluted from raw scrap tires even with water in the high concentration level. Many kinds of organic substances in raw scrap tires were pyrolyzed and removed from the active carbon produced by carbonization and steam activation.
