摘要
Abstract Copper oxide nanorods (CuOnrs), capped with cetyltrimethylammonium bromide (CTAB-CuOnrs), and polyvinyl pyrrolidine (PVP-CuOnrs) were utilized to study the interaction of Aldicarb (A.D.) and Chlorpyrifos (C.P.) pesticides. Field-emission scanning electron microscopy and transmission electron microscopy studies confirmed the nanocrystalline structure of CuOnrs, CTAB-CuOnrs, and PVP-CuOnrs as having rod-like structures. The contact angle study showed the hydrophilic nature of the uncapped CuOnrs and PVP-CuOnrs with contact angle of 51° and 57°, respectively, while CTAB-CuOnrs exhibited hydrophobic nature with a contact angle of more than 90°. Interaction study of CuOnrs, CTAB-CuOnrs, and PVP-CuOnrs with A.D. and C.P was conducted using UV-Vis absorption study (in the 250 - 400 nm region). CuOnrs have shown the specific interaction with A.D., while CTAB-CuOnrs have shown with C.P. without using any bio-recognition elements. PVP-CuOnrs did not show systematic change with both pesticides confirming the capping agent-dependent specific interaction of the pesticides.
