Abstract
There is provided a process for removing trinitrotoluene from waste water resulting from the manufacture of trinitrotoluene, the process comprising forming an admixture of the waste water and an amino group containing compound of the formula (C.sub.n H.sub.2n+1).sub.m (NH(CH.sub.2).sub.x).sub.y NH.sub.z, wherein n is 1 to 25, m is 1 to 3, x is 1 to 5, y is 0 to 5, z is 0 to 2 or the amine and a cationic compound of the formula (C.sub.n H.sub.2n+1).sub.4 N.sup.+ X.sup.-, wherein n is 1 to 25, and X.sup.- is Cl.sup.-, Br.sup.-, SO.sub.4 H.sup.- ; stirring the mixture to form a water insoluble reaction product of trinitrotoluene, and recovering the reaction product from the substantially trinitrotoluene free waste water.
