چکیده
|
A sampling has been undertaken to investigate the variation of haloacetic acids formation and nature organicmatter through 81 samples were collected from three water treatment plant and three major rivers of tehran iran.changes in the total organic matter (toc), ultraviolet absorbance (uv254), specific ultraviolet absorbance (suva)were measured in raw water samples. haloacetic acids concentrations were monitored using a new staticheadspace gc-ecd method without a manual pre-concentration in three water treatment plants. the averageconcentration of toc and haas in three rivers and three water treatment plants in spring, summer and fall, were 4,2.41 and 4.03 mg/l and 48.75, 43.79 and 51.07 ?g/l respectively. seasonal variation indicated that haas levels weremuch higher in spring and fall.
