Abstract

Method for eliminating aromatic amines from the waste water by way of introducing aromatic mono- or poly-isocyantes at a molar ratio of 1: 1 //c 30 and separation of the resulting sediment. The aromatic isocyantes are introduced in a solid state or in the form of solutions in inert organic solvents.
