Nanomaterial-Agrichemical Interactions: Association Of Environmental Herbicides With Two-Dimensional Graphene Nanoplatelets, Nudar A. Bhuiya

The Journal of Purdue Undergraduate Research

Atrazine and glyphosate are the two most common agricultural herbicides used in the United States. Both herbicides can move in the environment, which results in contamination of drinking water sources. Graphene nanoplatelets (GNPs) are an emerging nanoparticle with potential uses for the remediation of environmental contamination. The first aim of this study was to determine binding interactions between atrazine and GNPs to mimic a mixture composition. To determine binding interactions, GNPs with different functional groups (none, carboxylated, or aminylated) were evaluated. GNPs at concentrations of 0, 0.5, 1, 2, or 3 mg/ml were incubated with atrazine at 3 ppb (μg/L) …
