The object of this project was to develop analytical methods for those pollutants in industries wastewater. The target compounds including Benzidine, N-Nitrosodiethylamine, N-Nitrosodimethylamine, 4-Aminobiphenyl, Benzo[a]pyrene, 2-Naphthylamine, Hexachlorobenzene, Ethyl carbamate (Urethane), Ben[a]anthracene, Di(2-ethylhexyl)phthalate, Dimethylformamide, Ethyl methanesulfonate, N-methylpyrrolidone, N-Methylformamide and Dimethyl acetamide. In thos project use the GC/MS, GC/MS/MS, LC/MS/MS to estabalish the detection of method limit. Each compound has a calibration curve with 決定係數R2>0.99 or higher. The method RSD is 20%, and the instrument signal to noise ratio (S/N) of the DL is 2.5. Most of 15 objects have reached the limit requirement of the water pollution method., except the Di(2-ethylhexyl)phthalate. The concentration of Di(2-ethylhexyl)phthalate in the method blank exceeds the limit requirement of the water pollution method. Although the experimental vessels were rinsed with acetone, the noise could not be completely eliminated. According to the World Health Organization, 2003, the concentration of phthalate esters in the city is about 5~132 ng/m3 (Cautreels W et al., 1977, Bove JL et al., 1977). The analytical method developed in this project were proven to be pratical by surveying at 3 field samples, each compounds at leat 1 field sample. Establish analysis method for target pollutants and developing 5 kinds of standard analysis methods for EPA.
