Description
| - This article describes a new simple method for dehalogenation of 4-halogenoanilines in buffered aqueous solution using a reduction technique based on the treatment with the metallic alloy in alkaline conditions at room temperature. Al and Zn metals and Al-Fe, Al-Ni, Cu-Sn, Cu-Zn and Al-Cu-Zn metallic alloys were tested as the reductants. The GC-MS and 1H NMR spectroscopy were used for analyzing the reaction mixtures, and aniline was detected as the single product of the reduction of mentioned 4-halogenoanilines. It was observed that the addition of the metal chelating agent is essential for the complete dehalogenation of halogenated anilines in buffered solutions. The possibility of lowering of aniline and Ni2+ content in the aqueous solution was tested using flocculation and extraction.
