| 摘 要： | 从理论和样品分析两方面比较了ATR/FTIR技术和红外透射法,并分别用这两种红外技术测定了蔬菜中氯氰菊酯含量.结果表明:氯氰菊酯在916cm-1处的吸收峰不受青菜叶谱图干扰,可选择此峰为定量分析波数.以峰面积定量,运用ATR/FTIR技术和红外透射法分别得到峰面积Y和样品浓度X的线性方程:y=1.423x-0.0021,相关系数R=0.9979;y=26.025x-2.2847,相关系数R=0.9971,其最低检出线分别为0.01 mg和0.15 mg.ATR/FTIR技术相对于传统红外透射法其测定灵敏度更高,且完全不需对样品进行预处理.

| Abstract: | The paper compares technology between ATR/FTIR and infrared transmission on determining pesticides in vegetables from theory and analytical technique. Experiments show that the absorption peak of Cypermethrin at 916 cm-1 is independent and can be used as the characteristic absorption peak for the qualitative and quantitative determination.To quantitative peak area, the use of ATR / FTIR technology and transmission were to be as follows equation: y=1.423x-0.0021, correlation coefficient R=0.9979, y= 26.025x-... |
