High concentrations of cyanide in soil can result from contamination by road salt, electroplating waste, and residuals from manufactured gas plant sites. The most toxic species is “free” cyanide (CN_, HCN), but this form is generally rare in contaminated soil and groundwater. Iron cyanides are often predominant in environmental samples and have low toxicity. Unfortunately, free cyanides are the thermodynamically favorable species in solution, and degradation of iron cyanide compounds to the free cyanides can be accelerated by sunlight and microorganisms. There were two objectives of this research project. The first objective was to investigate the potential for phytoremediation of ...
