Abstract

建立永春芦柑(Citrus Reticulata Banco)2,4-二氯苯氧乙酸(2,4-D)残留量高效液相色谱(HPLC)测定方法.样品用乙酸乙酯超声波提取,对比C18、硅胶、硅藻土三种固相萃取柱净化效果,洗脱液2,4-D富集10倍后HPLC检测.HPLC条件:C18色潜柱;波长230nm;流动相为60％甲醇-pH2.5磷酸水溶液.2,4-D的线性范围1.00～20.00mg·kg-1,线性相关系数0.9998.合理用药时芦柑果皮2,4-D残留量0.74 mg·kg-1,芦柑2,4-D含量0～0.75 mg·kg-1,变异系数1.4％～5.5％,2,4-D回收率86％～92％.
