摘要: |
采用顶空-气相色谱法测定地表水中乙酸酯类化合物,并对顶空瓶的加热温度、平衡时间进行优化。优化后,方法在6种乙酸酯类化合物质量浓度0.05~1.00 mg/L范围内线性良好,检出限为4.49~58.5 μg/L,RSD为0.61%~2.51%,加标回收率为96.5%~104%,方法便捷、环保、经济,适用于地表水中乙酸酯类的检测。 |

Abstract: |
A method for the determination of acetic acid esters in surface water by headspace gas chromatography was developed. The heating temperature and equilibration time of the headspace bottle were optimized. After optimization, the method showed good linearity in the mass concentration range of 0.05~1.00 mg/L, the detection limits were 4.49~58.5 μg/L, the RSD ranged from 0.61%~2.51%, and the recovery rates were between 96.5%~104%. The method is convenient, environment-friendly, economic, and suitable for the determination of acetate esters in surface water. |
