Abstract
Cyanopropyl-functionalized nanosilica based dispersive micro-solid phase extraction method for rapid removal of organophosphorus pesticides from water samples
Highlights
Pesticides are a large group of hazardous organic compounds that are utilized on farms as herbicides, fungicides, and insecticides [1,2,3,4]
This study focused on the functionalization of silica nanoparticles with polar cyanopropyl moieties (CNPr@SiO2 NPs) that was tailored for use as a dispersive micro-solid phase extraction (D-μ-solid phase extraction (SPE)) adsorbent
The Fourier transform infrared (FTIR) spectrum of CNPr@SiO2 NPs (Fig. 1D) shows peaks at 3,390 and 1,634 cm–1 for O–H stretching, Si–O stretching band appears at approximately 1,100 cm–1 and the cyano groups (C≡N) stretching at 2,246 cm–1
Summary
Pesticides are a large group of hazardous organic compounds that are utilized on farms as herbicides, fungicides, and insecticides [1,2,3,4]. Organophosphorus pesticides (OPPs) are extensively applied in agriculture to protect crops from insects damage and improve their quantity and quality [5,6]. Their residues are a major source of environmental contamination, as they can be migrated from soil and air into the water resources during their usage. The United States Environmental Protection Agency (US-EPA) has classified most of OPPs as highly or moderately toxic substances [7,8]. According to the established regulation by the European Union (EU Directive 98/83/EC), the maximum acceptable level for individual and total pesticides in drinking water is 0.10 and 0.50 μg L–1, respectively [9].
