| 英文摘要 | This study developed a new method on the determination of carcinogenic disinfection by-products (DBPs)-trace dichloroacetic. acid and trichloroacetic acid in lap water by ion chromatography-electrospray-tandem mass spectrometry (IC-ESI-MS/MS). The separation of two haloacetic acids (HAA2) and the KOH gradient eluents were generated by Eluent Generator of ICS-3000. After the suppressor in which the eluents were suppressed to be neutral pH, AP13200 ESI-MS/MS was employed to detect and measure analytes under appropriate MS conditions without adding any organic solvent. In the case of HAA2, optimised IC and MS parameters including eluent gradient, temperature and collision energy etc. brought high sensitivity in which the minimal detection limits (MDLs) of DCAA and TCAA were 0.053 g/L and 0.46 g/L while the correlation coefficients (R) of calibration curves who that might calibrate over two orders of magnitude were 0.9999 and 0.9992 respectively. Relative standard diviations of the peak area for nine successive injections of four-different-concentration standard solutions and two actual samples were all lower than 7%. Over than 60 tap waters samples that were collected from 18 boroughs or counties in Beijing and other cities or towns in China were chosen fro the measurement, the results were satisfied. The recoveries of spiked standard were between 86.7% and 119.0% for five typical samples multiply at four different standard concentrations. |
