　　有机氟农药主要有氟乙酰胺、氟乙酸、氟乙酸钠，价格低廉，溶于水，容易配制，鼠类易接受，是灭鼠的有效药物，但因毒性大，具有二次中毒的特点，对人畜毒害较大。中毒生物体内主要以氟乙酸根的形式存在。氟乙酸可以直接用离子色谱法直接测定，对于氟乙酰胺可以用碱将其转化成氟乙酸根离子进行检测。

　　氟乙酸钠成为刑事中毒案件中常见的毒物之一。GC法是目前检测氟乙酸钠zui灵敏的方法，但该方法须衍生化处理，步骤相对繁琐，相比较来说离子色谱法是比较简单，灵敏度又高的一种方法。

　　检测食物里面的氟乙酸，容易受甲酸丙酸的干扰，需要选择合适的淋洗液条件，本文采用四硼酸钠作为淋洗液,能很好地解决各个离子对氟乙酸的影响。

　　氟乙酸的检测一般都需要到现场直接检测，可以采用普仁仪器的便携离子色谱，随提随走，操作简单便捷。

　　实验条件

　　仪器：离子色谱仪PIC

　　柱子：阴离子色谱柱PRA-10

　　淋洗液：四硼酸钠

　　流速：1.0mL/min
