摘要

利用氧化铜无帽纳米棒（UC-CuO）、十六烷基三甲基溴化铵帽（CTAB-CuO）和聚乙烯吡咯烷（PVP-CuO）研究了涕灭威（A.D. ）和毒死蜱（C.P. ）农药的相互作用。电子显微镜（FE-SEM & TEM）研究证实了 UC-CuO、CTAB-CuO 和 PVP-CuO 的纳米晶体结构和纳米棒形态。接触角研究表明，UC-CuO 和 PVP-CuO 具有亲水性，接触角分别为 51°和 57°。而 CTAB-CuO 具有疏水性，接触角超过 90°。利用紫外可见吸收研究（250-400 纳米波段）对 UC-CuO、CTAB-CuO 和 PVP-CuO 与 A.D. 和 C.P. 的相互作用进行了研究。UC-CuO 显示了对 A.D. 的特异性检测，而 CTAB-CuO 则在不使用任何生物识别元素的情况下显示了对 C.P. 的特异性检测。PVP-CuO 对两种杀虫剂都没有显示出系统性变化，这证实了杀虫剂的特异性相互作用取决于封端剂。

Interaction Studies of PVP and CTAB Capped CuO Nanorods with Aldicarb and Chlorpyrifos

Copper oxide uncapped nanorods (UC-CuO), capped with cetyltrimethylammonium bromide (CTAB-CuO), and polyvinyl pyrrolidine (PVP-CuO) were utilized for interaction study of Aldicarb (A.D.) and Chlorpyrifos (C.P.) pesticides. Electron microscopy (FE-SEM & TEM) studies confirmed the nanocrystalline structure and nanorod morphology of UC-CuO, CTAB-CuO, and PVP-CuO. The contact angle study showed the hydrophilic nature of the UC-CuO and PVP-CuO with contact angle of 51° and 57°, respectively. While CTAB-CuO exhibited hydrophobic nature with a contact angle of more than 90°. Interaction study of UC-CuO, CTAB-CuO, and PVP-CuO with A.D. and C.P was conducted using UV–vis absorption study (in the 250–400 nm region). UC-CuO showed the specific detection with A.D., while CTAB-CuO have shown with C.P. without using any bio-recognition elements. PVP-CuO did not show systematic change with both pesticides confirming the capping agent-dependent specific interaction of the pesticides.
