Abstract
A method to determine residues of diflubenzuron (DFB), teflubenzuron ( TFB), triflumuron (TFM) at 0.01 ppm with recoveries above 60 % in appl e and pear pulps for baby food is described. DFB, TFB and TFM are extr acted with methanol, and cleaned up by SPE using C18 stationary phase and methanol mobile phase. Analysis of the three pesticides is by SFC- UV at 254 nm using a Diol column, and CO2 at 30 MPa and 40 degrees C m odified with acetonitrile (10 %) mobile phase.
