    摘要:

    用近紅外光譜(NIR)方法對(duì)溶液中極微量毒死蜱進(jìn)行了測(cè)定,,通過(guò)模擬蔬果成分背景,,配制了47個(gè)混合液樣本,,其中37個(gè)樣本為含有質(zhì)量比為0.005~0.100mg/kg毒死蜱的混合液樣本,用于定量分析,同時(shí)10個(gè)不含農(nóng)藥的混合液樣本,用于聚類分析,。結(jié)果表明,,近紅外光譜法對(duì)混合溶液中質(zhì)量比在0.008~0.090mg/kg之間的毒死蜱取得良好的檢測(cè)效果,。

    Abstract:

    This paper demonstrated the detecting of chlorpyrifos at trace level in pesticide solution based on near infrared (NIR) method. Forty seven samples were prepared by simulating vegetables and fruits ingredient, thirty seven of which were used for quantitative analysis. The range of chlorpyrifos consistency was from 0.005mg/kg to 0.100mg/kg, Other samples with no pesticide were used for cluster analysis. The results showed that NIR method is appropriate to analyze the mixing solution containing traces of chlorpyrifos (between 0.008mg/kg and 0.090mg/kg).
