摘要
采用电感耦合等离子体-质谱法(ICP-M S)测定水中的钼、钴、铍、锑、镍、钡、钒、钛、铊等9种元素。结果表明,各元素检出限0.005—0.07μg.L-1,满足饮用水源分析要求;空白加标回收率94.2%—106.0%,相对标准偏差RSD<4.0%,n=9)。样品加标回收率93.8%—110.0%,该方法高效、简便、线性范围宽,适用于饮用水源水质分析。
The trace elements in water,including molybdenum,cobalt,beryllium,antimony,nickel,barium,vanadium,titanium and thallium,were determined by inductively coupled plasma-mass spectrometry（ICP-MS）.The limitation of detection for elements were 0.005—0.07μg·L-1,which met the need of drinking water source analysis.The black standard addition recovery were 94.2%—106.0%.The relative standard deviations（n=9）were under 4.0%.The sample standard addition recovery were 93.8%—110.0%.This method is simple,rapid,accurate characteristics,and that suits to analyze the quality of drinking water and its source analysis.
