Abstract:

To develop a new method based on matrix solid-phase dispersion(MSPD) extraction with basic aluminum oxide-graphitized carbon black to determine abamectin in different vegetables. The abamectin was analyzed by HPLC/MS. Optimization of different parameters such as the ratio of HPLC mobil phase, the type of solid supports for matrix dispersion, the ratio of sample and sorbent, different eluent and dosage was carried out. The results showed that the recovery range was 80.4%～103.6 %with relative standard deviation lower than 8%. It proved that MSPD is a valid method to analyse abamectin for fresh vegetables.
