| 摘 要： | 以ClC-ODS(150mm×6.0mm,5μm)为色谱柱,V(甲醇)∶V(水)(φ=0.2%氨水溶液)=55∶45为流动相,其体积流量为0.8mL/min;用SPD-6AV紫外检测器检测波长为270nm,柱温为室温,灵敏度为0.16AUFS.实验表明,吡虫啉的线性方程为A=481586.1c-2381.26,r=0.9989,回收率为108%,RSD=2.56%;巴沙的线性方程为A=74333.36c-686.096,r=0.9975,回收率为106%,RSD=0.34%;吡虫啉的相对标准偏差RSD=0.187%,巴沙的相对标准偏差RSD=2.29%;并对流动相和检测波长进行了优化,确定了最佳的流动相和检测波长.

| Abstract: | Taking method HPLC ODS- column,with methanol-water(0.2% ammo ni a water solution) 55/45 as mobile phase with UV dection at 270 nm, and room temp erature, the results were as follows:midacloprid's equation liner A=481 586.1c- 2 381.26, related coefficient r=0.998 9, recyclable rate=108 % ,and RSD=2.56 % ; baycarb's equation liner A=74 333.36c- 686.096, related coefficient r=0. 997 5, recyclable rate=106 % , and RSD=0.34 % . The conclusion is: the method supplies scientific reference according to determination of Chonglingmie. |
