Abstract

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
