摘要
采用二氯甲烷液液萃取—氮吹浓缩—丙酮定容去除干扰物,用气相色谱检测水中的阿特拉津,根据保留时间定性,外标法定量。本方法适用于水中阿特拉津的残留量分析,最低检测浓度为4.51×10-2μg?L。
The methylene chloride liquid-liquid extract and so on are used to remove the disturbing materials,and the gas chromatography is used to determine Arab League Tela Tianjin in the water according to the retention time qualitative and the external standard of legal measures. This method is suitable for the analysis of Arab League Tela Tianjin remains in the water, with the lowest examination density being 4.51 ×10^-2μg / L.
