| 摘 要： | 以阳离子型微乳液ＣＰＣ／正戊醇／正已烷／水为介质，进行了α－ＴＮＴ－Ｎａ２ＳＯ３分光光度法的研究（ε＝３．０６５×１０４Ｌ·ｍｏｌ－１·ｃｍ－１）与以ＣＰＣ为介质（ε＝２．６４４×１０４Ｌ·ｍｏｌ－１·ｃｍ－１）比较，测定灵敏度明显提高，α－ＴＮＴ在０．０５～２０μｇ／ｍＬ范围内符合比耳定律．相对标准偏差０．１９７％．该法成功地应用于污染土壤中及合成水样中α－ＴＮＴ的测定．

The Determination of α-TNT by Na_2SO_3-oil/water Cationic-microemulsion System |

| Abstract: | In the medium of O/W cation-microemulsion CPC/n-C5H11OH/n-C6H14/H20,α-TNT-sodium sulfite system was studied.The sensitivity of determination in CPC/n-C5H11OH/n-C6h14/H2O microemulsion was higher than that in CPC solution.The molar absorption coefficient was 3.065+104L·mol-1cm-1.Beer's law was obeyed on the concentration range of 0.05-20ug/ml.The relative standard deviation was 0.197%.This method was applied to the determination of x-TNT in the contaminated soil and wastewater.The results was satisfactory. |
