| 中文摘要 | a simple and fast method for trace speciation analysis of mercury (hg2+), methylmercury (mehg+) and ethylmercury (ethg+) in seawater has been developed by short-column high-performance liquid chromatography hyphenated to inductively coupled plasma spectrometry (hplc-icp-ms) after on-line cation-exchange column (cec) preconcentration. the analytes were firstly adsorbed on the cec without any extraneous reagent, and then were eluted rapidly (within seconds) and completely with a very low concentration of l-cysteine solution, which provides the conveniency for the on-line coupling of the preconcentration method and detection technique. to our best knowledge, it is for the first time to employ the cec preconcentration technique to trap all of the three mercury species simultaneously at their positive charged status for the purpose of speciation analysis. under the optimized conditions, a very high preconcentration factor up to 1250 has been obtained with 30 ml sample solution, which leads to the very low detection limits of 0.042 rig l-1 for hg2+., 0.016 ng l-1 for mehg+ and 0.008 ngl(-1) for ethg+ (as hg), respectively. with the established method, three seawater samples were also analyzed, and all the three mercury species have been found in each sample, albeit at a very low concentration. crown copyright (c) 2011 published by elsevier by. all rights reserved. |
