用带荧光检测器及柱后衍生化装置的高压液相色谱仪测定了培福朗(iminoctadinctriacetate)在苹果和土壤中的残留及苹果中的消解动态。两年的试验结果表明,培福朗在苹果中的消解速度是较缓慢的,培福朗在苹果中的半衰期为7天。在整个苹果生长期,使用培福朗1000μg/g,500μg/g 和250μg/g 涂抹两次,喷雾一次,最后一次施药距采收间隔期为22～192天,培福朗在苹果和土壤中的残留量均低于最小检出限量。 The residues of iminoctadinctriacetate in apples and soil and the digestion dynamics in apples were determined by HPLC with fluorescence detector and column derivatization. The two-year trial showed that Pefloxacin digestion was slower in apples and that Peifloran had an apple half-life of 7 days. Pefloxacin 1000 μg / g, 500 μg / g and 250 μg / g were applied twice in the whole growth period of apple and sprayed once. The last application was taken within 22-192 days from the harvesting interval. Peifulun was applied in apples and soil In the residual amount of less than the minimum detection limit.
