报道了扑菌唑的代谢产物2 ,4 ,6 -三氯苯酚在土壤和蘑菇中的残留测定方法。样品以丙酮提取 ,二氯甲烷萃取 ,吡啶盐酸盐水解 ,气相色谱测定 ,最小检测量为0.19×10-12 g。土壤和蘑菇中的最低检测浓度为0.0002mg/kg,添加标准样品的回收率和变异系数分别为89.68 %~96.20 %和1.75 %~3.20 %。
The method for determining the residues of 2,4,6 - trichlorophenol in soil and mushrooms was reported. The samples were extracted with acetone, extracted with methylene chloride, hydrolyzed by pyridine hydrochloride and detected by gas chromatography. The minimum detectable amount was 0.19 × 10-12 g. The lowest detection concentration in soil and mushroom was 0.0002mg / kg. The recoveries and coefficients of variation of standard samples were 89.68% -96.20% and 1.75% -3.20% respectively.
