A SPE-HPLC-ESI(+)-MS method for the determination of thifensulfuron-methyl residues in soil,corn grains and plants was developed.Residue dynamics in soil and the final residues in soil,corn grains and plants were evaluated.The residue of thifensulfuron-methyl in samples(corn grains,plants and soil)was extracted by a mixture of acetonitrile and phosphate buffer(pH 7.8)=2∶8(V/V),vortex and ultrasonic,and then the extracts were adjusted to low pH and passed through a C18 solid phase cartridge… CONTINUE READING
