Treating hazarous materials

Abstract

Methods of treating hazardous materials, such as, for example, contaminated soils, are disclosed. In one aspect, a method may include treating a contaminated soil with a hazardous material treatment composition to form a resulting material. In one aspect, the hazardous material treatment composition may include mostly salt, and from 0.5 to 15 wt % sorbent. The method may further include treating the resulting material with one or more inorganic binding agents. Other methods of treating hazardous materials are also disclosed, as well as compositions for treating hazardous materials.

1 - 17 . (canceled)  
   
   
       18 . A composition comprising: 
 at least 75 wt % salt, the salt including: 
 monovalent cation halide salt;  
 polyvalent cation halide salt;  
 sulfate salt; and  
 magnesium salt;  
   0.5 to 15 wt % sorbent; and    a sufficient amount of base to give the composition a pH greater than 10.    
   
   
       19 . The composition of  claim 18 , further comprising: 
 sodium chloride present in highest concentration;    an anti-corrosion agent;    from 1 to 5 wt % sorbent, wherein the sorbent comprises zeolite.    
   
   
       20 . The composition of  claim 18 , further comprising contaminated soil and an inorganic binding agent mixed with the salt, the sorbent, and the base.
