Description

一种测定福美甲胂含量的高效液相色谱法
技术领域
本发明属于色谱分析领域,具体涉及一种测定福美甲胂含量的高效液相色谱法。
背景技术
福美甲胂学名为N,N-二甲基二硫代氨基甲酸甲胂。在农业上主要用作保护性杀菌剂,可防治多种农作物真菌性病害,对一些真菌性病害有特效,适用于果树、蔬菜及其他经济作物。2012年烟台苹果“套药袋”事件中就涉及到福美甲胂农药。福美甲胂等含砷农药由于其毒性和环境风险,国家已经禁用了。但在个别农作物产区、个别农户仍有使用情况。加强对福美甲胂的风险监测尤为必要。
目前尚没有报道福美甲胂的测定方法。与福美甲胂同为有机胂类农药的福美胂的测定方法有相关报道,主要有液相色谱法和液相色谱串联质谱法,但液相色谱法测福美胂的灵敏度较低,而液相色谱串联质谱法虽然在灵敏度上大大提高了,但仪器设备昂贵。
本发明提出了一种福美甲胂测定方法。
发明内容
本发明的目的在于提供一种适用范围广、重现性好、灵敏度高的福美甲胂测定方法。为农产品中福美甲胂的风险监测提供有益借鉴。
为实现上述目的,本发明采用如下技术方案:
一种测定福美甲胂含量的高效液相色谱法,包括:
(1)称取0.1~1.0g碘,加入100mL甲醇,超声溶解后用水定容至1000mL配制成碘溶液;
(2)向盛有福美甲胂的进样小瓶内加入0.01~0.05mL碘溶液,待测溶液与碘溶液的体积比为100:1~20:1,在40~60℃水浴中反应10min后取出待测定;
(3)将待测溶液通过自动进样器引入高效液相色谱仪,通过苯基色谱柱分离后,在270~330nm波长下测定。
本发明的有益效果在于:
利用碘衍生的方法实现对福美甲胂含量的测定,方法操作简便,适合福美甲胂含量的测定。
附图说明
图1为实施例2中福美甲胂衍生后色谱图。
具体实施方式
为了使本发明所述的内容更加便于理解,下面结合具体实施方式对本发明所述的技术方案进一步的说明,但是本发明不仅限于此。
实施例1

称取0.1g碘,加入100mL甲醇,超声溶解后用水定容至1000mL配制成碘溶液;向盛有福美甲胂的进样小瓶内加入0.01mL碘溶液,待测溶液与碘溶液的体积比为100:1,在40℃水浴中反应10min后取出待测定。将待测溶液通过自动进样器引入高效液相色谱仪,通过苯基色谱柱分离后,在270nm波长下测定。
实施例2
一种测定福美甲胂含量的高效液相色谱方法

实施例3
一种测定福美甲胂含量的高效液相色谱方法
称取1.0g碘,加入100mL甲醇,超声溶解后用水定容至1000mL配制成碘溶液;向盛有二硫代氨基甲酸盐类化合物的进样小瓶内加入0.05mL碘溶液,待测溶液与碘溶液的体积比为20:1在60℃水浴中反应10min后取出上机测定。将待测溶液通过自动进样器引入高效液相色谱仪,通过苯基色谱柱分离后,在330nm波长下测定。
以上所述仅为本发明的较佳实施例,凡依本发明申请专利范围所做的均等变化与修饰,皆应属本发明的涵盖范围。
