将阿特拉津印迹聚合物粒子分散在邻苯二甲酸二辛酯增塑剂中，然后包埋在聚氯乙烯基质中，研制了一种仿生电位型传感器。该传感器对阿特拉津的响应范围为0.0001~10 mm，响应范围为pH 2.5~3.0，检测下限为0.5µM(0。百万分之一)。该传感器具有相当快的响应时间，与其他重要类别的农药和除草剂相比，响应时间接近2分钟，并且具有高选择性。通过添加已知数量的阿特拉津，该传感器成功地用于地下水中阿特拉津的现场监测。(C)2006爱思唯尔B.V.保留所有权利。
A biomimetic potentiometric sensor was developed by dispersing the atrazine imprinted polymer particles in di-n-octyl phthalate plasticizer and then embedding in polyvinyl chloride matrix. The sensor responds to atrazine in the pH range 2.5-3.0 over a wide working range of 0.0001-10 mM with a detection limit of 0.5 mu M (0. 1 ppm). This sensor has a reasonably faster response time of similar to 2 min and high selectivity with respect to other important classes of pesticides and herbicides. The utility of the sensor was successfully tested for field monitoring of atrazine in ground waters by spiking known amounts of atrazine. (c) 2006 Elsevier B.V. All rights reserved.
