Sequential Speciation Analysis of Heavy Metals in Drinking Water Pipe Scales by Mass Spectrometry
文献摘要：
A n electrochemical mass spectrometry technique was developed based on a homemade analytical device for sequential analysis of the heavy metals with various speciations in the scales.Four speciations(e.g.,water-soluble speciation,organic speciation,indissoluble speciation and elemental speciation)of heavy metals are sequentially extracted by H2O,CH3OH,EDTA-2Na and electrolysis for online electrospray ionization mass spectrometry(ESI-MS)detection.The method takes significant advantages,such as requiring no tedious offline sample pretreatment,high speed of analysis(20 min),high throughput(multi-metals),good sensitivity(0.5 μg/L)and rich chemical information(four speciations).As a result,the rapid comprehensive characterization of four speciations of Pb,Ni,Cu,Zn,Fe,Ba,Mn,Cr and Ca in water pipe scales has been qualitatively achieved.It demonstrated that the present method is a powerful tool for the effective assessment of potential hazards in drinking water,which provides a new analytical idea for evaluating water quality.
