| 英文摘要 | analysis of trace zn2+ by capillary electrophoresis with field-amplified sample stacking(fass) and high voltage capacitively coupled contactless conductivity detection(c4d) was presented. 2-(n-morpholino) ethanesulfonic acid(mes)/histidine (his) was used as the separation electrolyte. the effects of mes/his concentration in the sample matrix, and the injection time on the effective stacking efficiency, and the concentration of the separation electrolyte on the sensitivity were studied. zn2+ was dissolved in deionized water and separated in 10 mmol/l mes/his (ph = 4.9) buffer. the c4d using fass yielded sensitivity enhancement with respect to non-stacking injection mode in excess of three orders of magnitude (1.3 x 10(3)) and a limit of detection (lod) 5 nmol/l to zn2+. there was a linear relationship between the response of peak area and concentration of zn2+ in the range from 10 to 1 000 nmol/l(r=0.9995). the method can be used for determination of zn2+ of trace level. |
