摘要
试验针对现存植物油中苯并(a)芘调控方法不足的问题,以大豆油为试材,经液-液萃取提取净化后,采用高效液相色谱检测分析苯并(a)芘含量方法,通过比较,10种不同吸附材料对苯并芘的吸附效率可以得出木质粉状活性炭的苯并(a)芘吸附率较高,为88.80%。选用木质粉状活性炭作为吸附剂进行试验,研究表明:木质粉状活性炭添加量为0.70%、吸附平衡时间45 min、吸附温度80℃、搅拌速率300 r/min对于苯并(a)芘吸附效果最好。解决了苯并(a)芘有效调控技术问题,为我国植物油安全评估与调控提供理论与技术依据。
Aimat the shortage of control methods of vegetable oils for benzo（a） pyrene in this paper.Soybean oil,as a test material,was analyzed benzo（a） pyrene by high performance liquid chromatography after the liquid-liquid extraction extracted and purified.By comparing adsorption efficiency to benzo（a） pyrene of 10 different adsorbent material under certain conditions,powdered activated carbon was selected as absorbent which showed the highest B（a）P adsorption rate of 88.80%.The wood powdered activated carbon was chosen as an adsorbent to make a single factor experiment.The optimal adsorption condition was decided：amount of activated carbon was 0.70%,adsorption equilibrium time was 45 min,adsorption temperature was 80℃,and stirring velocity was set as 300 r/min.Solve the benzo（a） pyrene and effective regulatory technical issues,and provide theoretical and technical basis for the safety assessment and regulation of vegetable oil.
