胺乙基硫代磷(膦)酸酯类化合物常用作农药中的杀虫剂。其残留量分析,可采用气液色谱法或比色法。但是灵敏度或排除杂质干扰方面仍不够理想。荧光法测定,灵敏度高,方法简便。我们利用离子交换法和离子交换柱上化学反应相结合的技术,富集与分离试样。此类化合物被吸附在柱上,它与银、氟离子作用生成氟磷(膦)酸酯后,再用去离子水洗脱。此氟磷(膦)酸酯与过氧化物反应生成的过氧磷(膦)
Amine ethyl phosphorothioate (phosphine) acid ester compounds commonly used pesticides in pesticides. The residue analysis, gas-liquid chromatography or colorimetric method. However, the sensitivity or the exclusion of impurities is still not ideal enough. Fluorescence determination, high sensitivity, the method is simple. We use ion exchange and ion exchange column chemistry combined with the technology, enrichment and separation of the sample. Such compounds are adsorbed on the column, which with silver, fluoride ions to generate fluorine phosphorus (phosphine) acid ester, and then with deionized water. The peroxophosphorus (phosphine) produced by the reaction of this fluorophosphorus (phosphonate) ester with peroxide,
