查询词典 sodium acetate

Samples were saponified with 20 g/L sodium hydroxide. The sexual hormones were then extracted with dichloromethane-acetic acetate (40∶1, v/v) under acidic conditions (pH 3, adjusted with 1 mol/L HCl ). An XTerraTMRP18 column was employed and a mixture of water-methanol-acetonitrile (50∶32∶18, v/v) was used as mobile phase. The seven sexual hormones were detected at 230 nm. The average spiked recoveries for the seven sexual hormones ranged from 75.6% to 97.8% with relative standard deviations of 1.9% to 7.2%. The linear ranges of determination were from 5 to 50 mg/L with correlation coefficients of 0.9999, and the limits of detection were from 3.7 to 12 ng.

先在试样中加入20 g/L氢氧化钠溶液与油脂进行皂化反应，然后用二氯甲烷-乙酸乙酯(体积比为40∶1)混合液在酸性条件下(pH 3)萃取，选择XTerraTMRP18色谱柱，以水-甲醇-乙腈(体积比为50∶32∶18)混合液为流动相，在波长230 nm处检测。7种性激素分离良好并排除了样品中杂质峰的干扰，低、高浓度平均回收率范围为75.6%~97.8%；相对标准偏差为1.9%~7.2%；检出限为3.7~12 ng。
