中文摘要：
以高容量、强亲水性的IonPac AS20（2mm）为分析柱，ESI-MS-MS串联质谱为检测器，同时测定瓶装水中的高氯酸盐和溴酸盐，该方法对高氯酸盐和溴酸盐的检出限（S／N=3）分别为0．01μg·l^-1和0．1μg·l^-1，线性相关系数分别是r=0．9990（0．05—100μg·l^-1）和r=0．9998（0．5—100μg·l^-1）．对某样品连续进样7次，高氯酸盐和溴酸盐的相对标准偏差（RSD）分别为1．2％和0．9％．运用该方法测定瓶装水，并加标回收，高氯酸盐和溴酸盐的加标回收率分别在101．0％-116．5％之间和87．5％-118．9％之间．
英文摘要：
A rapid method has been developped for the detemination of perchlorate and bromate in bottled-water samples by using ion chromatography/electrospray tandem mass spectrometry（IC/ESI-MS/MS） in the negative ESI and multiple reactions monitoring （MRM） mode. The method detection limits （S/N = 3） for perchlorate and bromate were 0. 01 μg·l^-1 and 0. 11μg·l^-1 respectively. A linear calibration was obtained with a corre- lation coefficient of 0. 9990 for perchlorate （ 0. 05--100μg·l^-1 ） and 0. 9998 for bromate （ 0.5--100μg·l^-1 ） . The relative standard deviation of the peak area for seven successive injections of bottled-water for perchlorate and bromate were 1.2% and 0.9%. The method was applied to simultaneously detect perchlorate and bromate in bottled-water samples. The recoveries of perchlorate and bromate were 101.1%-116.5% and 87.5%-118.9% respectively.
