代森锌在柑橘中的残留及消解动态研究
|
摘要
采用液相色谱(HPLC-UV)测定了代森锌在柑橘和土壤样品中的消解动态。柑橘和土壤样品经衍生净化、HPLC-UV检测。当代森锌在土壤和柑橘中的添加浓度为0.01～10.0 mg/kg时,其回收率为75.1%～80.6%之间,RSD为1.8%～5.6%;代森锌的LOD为2.0×10~(-10) g,在柑橘和土壤中的LOQ为0.01 mg/kg。消解动态试验结果显示,代森锌在柑橘和土壤中的消解动态规律符合一级动力学方程,半衰期为1.8～3.6 d。
The residual dynamics and final residues of zineb in citrus and soil samples in supervised field residue trials were determined by HPLC-UV.Citrus and soil samples were derivation,cleaned up and determined by HPLC-UV.Under the fortified level from 0.01 to 10.0 mg/kg for citrus and soil,the recoveris ranged from 75.1%to 98.7%with the relative standard deviations of 1.8%～5.6%.The LOD was 2.0×10~(-10) g,and the LOQ of the method was 0.01 mg/L for all samples.The results of dissipation dynamic test showed that the rules consistent with first order kinetics equation,and the half-life of zineb was 1.8～3.6 days.
