建立鹅肠中甲醛测定的新方法,采用凯氏定氮蒸馏装置代替蒸汽蒸馏装置从鹅肠中提取甲醛,并对水浴温度和时间进行改进。新建立的方法RSD为2.36%—4.23%,加标回收率为92.7%—102.3%,具有良好的线性范围,R~2=0.9999。方法精密度好,准确度高,适用于鹅肠中甲醛的测定。 A new method for determination of formaldehyde in goose intestine was established. Formaldehyde was extracted from goose gut by Kjeldahl nitrogen distillation instead of steam distillation and the temperature and time of water bath were improved. The RSD of the newly established method was 2.36% -4.23%, and the spiked recoveries ranged from 92.7% to 102.3% with a good linear range, R ~ 2 = 0.9999. The method has good precision and high accuracy and is suitable for the determination of formaldehyde in goose intestines.
