ICP-AES同时测定水中的痕量钼、钴、硼、锑、钒和钛

Determination of Trace Mo,Co,B,Sb,V and Ti in Water by ICP-AES

采用ICP-AES同时测定水中的痕量钼、钴、硼、锑、钒、钛等6种元素。结果表明,各元素检出限为1.5—13μg.L-1,满足饮用水及其水源水分析要求;空白加标回收率为94.2%—105%,样品加标回收率为90.6%—98.8%,相对标准偏差(n=9)<2.40%。该方法简便、高效、快速、线性范围宽,适于饮用水及其水源水质分析。

The trace elements in water,including Mo,Co,B,Sb,V,Ti,were determined by ICP- AES（inductively coupled plasma-atomic emission spectrometry）. The method has good precision and accuracy. The detection limits of elements are 1.5-13μg · L^-1, which meets the need of drinking water and its source analysis, The rates of blank standard addition recovery are 94.2%-105%. The rates of sample standard addition recovery are 90.6%-98.8 %. The relative standard deviations（n= 9） are under 2. 40%. This method is suitable for the drinking water with simple, rapid, accurate characteristics.
