摘要
The environmental contamination by explosives has concerned the scientific community, due to their toxicity, mainly in those areas where the explosives are manufactured, stored, or still demilitarized. This paper describes the RDX and TNT interaction in different matrices. The Freundlich isotherms were used for the data mathematical treatment. The results indicated that the largest adsorption and the smallest desorption of the RDX and TNT explosives occurred in the peat in natura, with adsorption coefficient (Kd) of 24.88 and Freundlich dessorption value 37.56 of RDX explosive, and adsorption coefficient (Kd) 78.11 and Freundlich desorption value 110,31 of TNT explosive.
