中文摘要 | 依序以含0.1% 醋酸之乙腈(v/v)溶液、丙酮、水及乙醚萃取農產品中亞速爛,再以矽酸鎂固相萃取匣及中性氧化鋁固相萃取匣淨化之,所得檢液以高效液相層析儀配合紫外光檢出器檢測。亞速爛添加0.1 ~ 0.3ppm濃度於柑橘中之平均回收率為83.5 ∼ 90.9% ,添加0.05 ~ 0.2 ppm 濃度於甘蔗中之平均回收率為80.6 ~86.7%,最低檢出量均為0.01 ppm 。 |
英文摘要 | Asulam was extracted with 0.1% acetic acid in acetonitrile, acetone, water and diethyl ether successively. Following after clean up with florisil and neutral alumina solid phase extraction cartridge, the elute was determined by HPLC with UV detector. Recoveries were carried out by spiking the standard asulam at the levels of 0.1~0.3 and 0.05~0.2 ppm to citrus and sugarcane, respectively. The average recoveries were 83.5 to 90.9 % for citrus and 80.6 to 86.7 % for sugarcane, and both detection limits was 0.01 ppm. |
