摘要
选择常温浸泡、索氏提取和超声波提取3种方式对3种保鲜膜中DOP进行分离提取,实验结果证明其差异性不显著,确定超声波提取方式最佳。
By using three methods of the room-temperature soaking, Soxhlet extraction and ultrasonic extraction, this paper makes the separation and determination of DOP in fresh-keeping film. The test results show that the difference of the three methods is not significant and the ultrasonic extraction is the best one.
