文摘
Soils and sediments near military sites where training regularly occurs are vulnerable to contamination from toxic nitro explosives such as 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). In order to clean up the explosive-contaminated soils, several options have been investigated and evaluated as ex situ remediation processes, including alkaline hydrolysis, subcritical water degradation, zero-valent iron (Fe(0)) reduction, and Fe(0)-assisted Fenton oxidation. The kinetics of the remediation processes were evaluated and the toxicity of treated solutions determined using the Microtox® bioassay.
