| Abstract: | A novel method for the determination of diafenthiuron in water using ionic liquid-based single drop liquid-phase microextraction-high performance liquid chromatography has been developed.The effects of different extraction conditions(solvent type and volume,drop volume,extraction time,stirring rates,temperature,salinity and so on) on extraction efficiency were investigated.The optimal experimental conditions were as follows: solvent type,solvent volume,drop volume,stirring rate,solution temperature,salinity... |
