| 摘 要： | 火炸药厂红水污染土壤中的主要污染物为二硝基甲苯磺酸盐DNTS,包括2,4-二硝基甲苯-3-磺酸盐(2,4-DNT-3-SO_3~-)和2,4-二硝基甲苯-5-磺酸盐(2,4-DNT-5-SO_3~-)2种异构体]。研究建立了振荡提取-高效液相色谱法测定土壤中DNTS的方法。4种土壤(黄土、棕土、红壤和黑土)和5个浓度水平(50、100、250、500、1 000 mg/kg)时,DNTS的回收率为69.4%~111%,变异系数为0.28%~6.62%(n=3)。应用该方法测定甘肃某火炸药厂红水污染土壤样品,2,4-DNT-3-SO_3~-和2,4-DNT-5-SO_3~-浓度实测值(平均值分别为505、25.2 mg/kg)重复性好,变异系数为1.29%和1.53%(n=3)。

| Abstract: | Dinitrotoluene sulfonates (DNTS) was the main pollutant of soils contaminated by TNT red water of explosive factory, including 2,4-dinitrotoluene-3-sulfonate (2,4-DNT-3-SO3-) and -5-sulfonate (2,4-DNT-5-SO3-). This paper introduced a new method for measuring DNTS in soils by oscillations extraction-high performance liquid chromatography. Under the conditions of 4 kinds of soils with five spiked concentrations (50, 100, 250, 500 and 1000 mg/L), the recovery rates of DNTS were 69.4%-111% with variation coefficients of 0.28%-6.62%. For the determination of DNTS in red water polluted soils from a explosives factory in Gansu province, variation coefficients of 2,4-DNT-3-SO3- (505 mg/kg) and 2,4-DNT-5-SO3- (25.2 mg/kg) concentrations was merely 1.29% and 1.53% (n=3), respectively. |
