摘要
采用超声波提取技术,用正己烷提取氧化塘出水中己二酸二(2-乙基己基)酯增塑剂,以气相色谱/质谱联用选择离子监测法检测,外标法定量。对己二酸二(2-乙基己基)酯的检出限为0.4μg·L^-1(S/N=3);回收率为90%~95%,相对标准偏差为5.02%。该方法简便、快速、准确,适用于氧化塘出水中己二酸二(2-乙基己基)酯的测定。
The di (2 - ethyl hexyl )adipate (DEHA) in oxidation pond water was extracted by hexane with ultrasonic generator. The determination of Di (2 - ethyl hexyl) Adipate was carried out by gas chromatography/mass with selected ion monitoring (SIM) mode, using external standard method. The detection limit of DEHA was 0. 4μg·L^-1( S/N = 3 ), recoveries were in the range of 90% - 95% , the RSD were in the range of 0. 12% -0. 28%. This method was of simple, fast, accurate which was suitable to the determination of Di (2 -ethyl hexyl) Adipate in Oxidation pond water.
