| 中文摘要 | ionic liquid based dispersive liquid-liquid microextraction (il-dllme) combined with high performance liquid chromatography-inductively coupled plasma mass spectrometry (hplc-icp-ms) for the determination of mercury species in liquid cosmetic samples is described. firstly mercury (hg(2+)), methylmercury (mehg(+)) and ethylmercury (ethg(+)) were complexed with ammonium pyrrolidinedithiocarbamate (apdc), and then the complexes were extracted into 1-hexyl-3-methylimidazolium hexafluorophosphate ([c(6)mim][pf(6)]) using dllme. under the optimized conditions, the enrichment factors of 760, 115, 235 for hg(2+), mehg(+) and ethg(+) were obtained from only 5.00 ml sample solution. the detection limits of the analytes (as hg) were 1.3 ng l(-1) for hg(2+), 7.2 ng l(-1) for mehg(+) and 5.4 ng l(-1) for ethg(+), respectively. the relative standard deviation (n = 10) of 0.5 ng ml(-1) hg(2+), mehg(+) and ethg(+) were 7.4%, 5.2% and 2.3%, respectively. finally, the developed method was successfully applied for the speciation of mercury in four liquid cosmetic samples, hg2+ was found as the main species in these samples, and a spike test was performed to verify the accuracy of the method. |
