산업폐수중의 염화페놀류 측정

Abstract

The most common five chlorophenols were monitored from the industrial waste water. By modified USEPA Method 3510, the samples were extracted with organic solvent, followed by analyzing using gas chromatograph/ mass spectrometer (GC/MS). The analysis were performed to the industrial wastewater which sampled from the paper and pulp, petrochemical, textile and dying, and leather industry. The comparison of the residue chlorophenols between before and after the treatment of waste water was performed. The limit of quantitation for 4-chloro-3-methylphenol, 2,4,6-trichlorophenol (2,4,6-TCP) and 2,4,5-trichlorophenol (2,4,5-TCP) was the concentration of 0.1 ng/mL and the one of 2,3,4,6-tetrachlorophenol and pentachlorophenol (PCP) was 0.5 ng/mL. 2,4,6-TCP was detected from samples most frequently. From the paper and pulp industrial wastewater, 2,4,6-TCP was monitored at 43% sites, and also other chlorophenols were detected more frequent than other industries. From the sample which was performed the waste treatment process, the concentration of cholorophenols was decreased remarkably. The results of the residual chrolophenols determination will be applied to trace the contamination sources and prevention of chlorophenols contamination.
