Remediation of Atrazine in Contaminated Soil by Nano Zerovalent Iron

Pesticide contaminated soil may require remediation to mitigate ground and surface water contamination. Nanoscale iron particles
(because of their large surface areas and high surface reactivity) represent a new generation of environmental remediation
technologies that could provide cost-effective solutions to some of the most challenging environmental cleanup problems. We
determined the effectiveness of nano zerovalent iron (nano ZVI) covered with urea-choline chloride to dechlorinate atrazine (2-chloro-
4ethylamino-6-iso-propylamino-1,3,5-triazine) in contaminated soil. This study determined the effects of nano ZVI and solution pH in
factorial design. Atrazine (0.4g/20g) was treated with 0.3g of nano ZVI (4.5%). Lowering the pH from 8.5 to 6 decreased the
destruction (concentration) of atrazine by nano ZVI. Our results indicate that nano ZVI can be used in alkaline soil to remediate
atrazine
