Piperazine pyridine in the paddy water insects - in the soil and residue analysis of rice plants

0.1 ~ 10mg / L range, in December 2009 WU Ping,[link widoczny dla zalogowanych], et al: piperazine pyridine insects in paddy water and rice plants in a soil residue analysis method for content and chromatographic peak area 39 showed a significant linear relationship, to meet of quantitative analysis L9J. Detection limit: 2.0 × 10. g. Minimum detectable concentration: soil, field water, plants were 0.02mg/kg. 2.5 recoveries and relative standard deviation according to the extraction, purification and determination of these steps, check the blank soil, field water,[link widoczny dla zalogowanych], plants to add recovery test. Set concentration of 0. O2, 2. O0mg/kg2 treatments, 5 replicates of each treatment,[link widoczny dla zalogowanych], the recovery results in Table 1. Table 1 shows, the average recovery of pyridine insect piperazine 85.98% ~ 101.28% in between the largest coefficient of variation was 9.04%,[link widoczny dla zalogowanych], the results show that the tests found pesticide residue analysis method requires L1 Ⅲ. Soil, water and plant fields to add liquid chromatography is shown in Figure 3.3 Conclusion The worm was first reported piperazine pyridine residue analysis. Add a blank field of soil water by
