| Abstract: | Analytical method for determining Thiacloprid residuce was established. A reverse HPLC system with a mixture of methanol / acetonitrile /water (30:10:60 V:V) as the mobile phase was used. The flow rate was 0.80 mL/min and the UV detection wave-length was 270 nm. The limit of detection (LOD) was 0.01 mg/L (r = 0.9999) with a recovery rate of 95.7%- 97.8% and RSD of 0.64% for 6 samples.The relationship between amount of thiacloprid and peak areas can be described using the linear equation: Y=1120.40 14541.15X. |
