本文叙述了一个定量、例行测定天然水中痕量四氯乙烯的快速方法。10毫升水样在反相高压液相色谱(HPLC)系统(十八硅烷,甲醇/水)中直接进样,用208nm紫外吸光进行测定,精度为±2.5％,检测限为每升水中0.06微克分子四氯乙烯,测定的浓度范围很宽(0.06—110μmol/l)。本方法已成功地应用于实际污染水样的测定,并讨论了这一技术在其它方面的应用。 This article describes a fast and accurate method for the quantitative and routine determination of trace tetrachlorethylene in natural water. A 10 ml water sample was injected directly into an RP-HPLC system (octadecane, methanol / water) and determined by UV-vis at 208 nm with a precision of ± 2.5% with a detection limit of 0.06 μg Molecular tetrachlorethylene, the measured concentration range is very wide (0.06-110μmol / l). This method has been successfully applied to the determination of the actual contaminated water samples and discusses the application of this technique in other aspects.
