Biological denitrification of hydrolysates from octahydro-1,3,5,7, tetranitro-1,3,5,7-tetrazocine
|
ABSTRACT: Alternatives for the destruction of common military explosives, including trinitrotoluene; hexahydro-1,3,5-trinitro-1,3,5-triazine; and octahydro-1,3,5,7 tetranitro-1,3,5,7-tetrazocine (HMX) are being investigated in the post-cold war period. One alternative combines chemical treatment (i.e., base hydrolysis of the explosives) and biological treatment (i.e., denitrification of the hydrolysate). This paper focuses on results of the biological part of the treatment process, during whi...
