| 摘 要： | 本文报导用导数示波极谱法直接测定农药中微量三氯乙醛的方法。实验结果表明,三氯乙醛在0.010mol/L NH_4Cl、5.00×10~(-4)mol/L EDTA和2.00×10~(-6)mol/L四乙基溴化铵组成的底液中,于滴汞电极上产生灵敏的峰电流。峰电位为-1.55V(Vs·S·C·E·)。检测下限为3.00×10~(-7)mol/L;浓度在3.00×10~(-7)～1.00×10~(-3)mol/L范围内与峰电流呈良好的线性关系。

| Abstract: | This paper reports a method for direct determination of trace trichloroacetadehyde InPesticide by derivative oscillographic Polarography. The result demonstrats that trichloroa-cetadehyde Produces a sensitive Peak current In the solution of 0.010mol/L NH_4Cl-5.00×10~(-4) mol/L EDTA 2.00×10~(-9) mol/L tetracethylammonium bromide. The Peak Potental is -1.55V(V. S. C. E.). The limit of detection for the trichloroacetadehyde is 3.00×10~(-7) mol/L. Theconcentration of trichloroacetodehyde is linear with peak current in the range 3.00×10~(-7)mol/L to 1.00×10~(-3) mol/L. |
