摘要
建立低共熔溶剂萃取,气质联用法测定水中的萘、芴、芘的分析方法。对低共熔溶剂的种类、混合比例、萃取方式、萃取温度等萃取条件进行选择优化。实验结果表明:比例为3:2的薄荷醇和癸酸的低共熔溶剂,30℃下在酸性环境中以旋涡混合进行萃取,萃取剂用量为500μL效果最佳。该方法检出限为0.01 mg/L,加标回收率为81.15%~91.49%。应用该方法对水样进行分析,具有成本低、方便快捷、绿色环保等优点。
A method of deep eutectic solvent extraction combined with GC-MS was established for determination of polycyclic aromatic hydrocarbons(PAHs), naphthalene, fluorene and pyrene in waste water.The analytical conditions such as types of eutectic solvents, mixing ratio, extraction method and extraction temperature were optimized. The experimental results show that the optimum dosage of extractant is 500 μL,when the ratio of menthol to decanoic acid is 3∶2 and the extraction temperature is 30 ℃ in acidic environment is mixed by eddies. The detection limit of this method is 0.01 mg/L, the recovery rate was 81.15%-91.49%.This method has the advantages of low cost, convenience and environmental protection.
