目前国外对于乙酰甲胺砱在植物上的残留量分析都采用碱金属热离子检测器或电子捕获检测器的程序升温气相色谱法。鉴于气相色谱法受设备条件的限制,推广有一定困难,我们试用薄层层析法,摸索了乙酰甲胺砱残留量的实验条件,得到了较为满意的结果。一、实验方法一、试剂与主要仪器1.乙酰甲胺砱标准溶液(1)1.0毫克/毫升乙酸乙酯溶液(2)0.1毫克/毫升乙酸乙酯溶液乙酰甲胺砱的纯度为99.5％,由江苏武进农药厂提供。2.溶剂乙酸乙酯、乙醚、丙酮、甲醇,36％乙酸,
At present, foreign countries for the acetaminophen residues in plants are analyzed using alkali metal ion detector or electron capture detector temperature-programmed gas chromatography. In view of the limitations of equipment conditions by gas chromatography, the promotion of a certain difficulty, we try the TLC method to explore the experimental conditions of acephate residues, get more satisfactory results. First, the experimental method First, the reagents and the main instrument 1. Acetyl methylamine 砱 standard solution (1) 1.0 mg / ml ethyl acetate solution (2) 0.1 mg / ml ethyl acetate solution Acetylated methylamine 砱 purity of 99.5% Provided by Jiangsu Wujin Pesticide Factory. 2. Solvents Ethyl acetate, ether, acetone, methanol, 36% acetic acid,
