Reactive atomized zero valent iron enriched with sulfur and carbon to enhance corrosivity and reactivity of the iron and provide desirable reduction products

Abstract

Iron, in the form of particles or iron wool, is used for the remediation of contaminated water. For ensuring that the process generally follows preferred chemical pathways resulting in non-toxic end products, and for providing greater rates of contaminant reduction, the iron is enriched with graphite carbon, at least 4% by weight, and sulfur, at least 0.5% by weight.

1 . A material for use in a water decontamination process comprises zero valent iron enriched with graphite carbon and sulfur. 
   
   
       2 . The material of  claim 1  wherein said iron is in the form of particles. 
   
   
       3 . The material of  claim 1  wherein said iron is in the form of iron wool. 
   
   
       4 . The material of  claim 1  wherein said carbon graphite comprises at least 4% by weight and said sulfur comprises at least 0.5% by weight.
