| Abstract: |
| A method was proposed that allowed the simultaneous determination of seven common anions, three inorganic disinfection by-products (DBPs) and five haloacetic acids (HAAs) in water samples by ion chromatography. Using the anion exchange column IonPac AS19 and KOH as eluent, large volume injection, all the compounds could be well separated and determined within 33 min by employing a concentration rate gradient. Limits of quantitative lower limits of the seven common anions were between 2.3 and 10.0μg/L, the three inorganic DBPs were between 3.3 and 10.0μg/L, and the five HAAs were between 5.3 and 34.3μg/L. The method was applied for determination of the source water and treated drinking water from the four waterworks of Hangzhou. Dibromoacetic acid was found in all the four waterworks, and three contain tribromoacetic acid, two contain chlorate, one contains trichloroacetic acid among the four waterworks. |
