分子印迹电化学传感器对苯醚菊酯的检测

应用热引发的方法研制了苯醚菊酯的分子印迹电化学传感器.用循环伏安法对影响该传感器制备的因素进行了优化，并对其性能进行了评价.实验表明：该传感器具有比较高的灵敏度和选择性，响应电流与苯醚菊酯的浓度在1.0~100.0 μmol/L成良好的线性关系，线性系数R为0.992 8,检出限为2.0 × 10-7 mol/L.将其应用于湘江水中苯醚菊酯的检测，回收率在95.62%~103.19%之间.     

Miticidal pyrethroids having an isobutyranilidoxime ether skeleton

Isobutyranilidoxime meta-phenoxybenzyl ethers and related compounds were synthesized. Their insecticidal activities measured against Periplaneta americana by injection were lower than that of phenothrin by factors of at least 1/60. However, some compounds were comparable to or only slightly less potent than phenothrin and tetramethrin in miticidal activity tested by a contact method against Dermatophagoides farinae, D. pteronyssinus and Tyrophagus putrescentiae. © 1998 SCI
