| Abstract: | A gas chromatography coupled with electron capture detector(GC-ECD) method was developed and applied to the analysis of nine haloacetic acids in drinking water.Various experimental conditions affecting the recovery rate of nine haloacetic acids were discussed.Under the optimized experimental conditions for sample pretreatment and GC-ECD measurement,the linear correlation coefficients for water samples are more than 0.99,and recovery rate range from 88% to 109%. |
