title: Efficient degradation of Rhodamine B by using ethylenediamine-CuCl2 complex under alkaline conditions.
abstract: In this work, we have developed a simple and efficient approach to the degradation of organic dyes using ethylenediamine-CuCl(2) complex as the catalyst under basic conditions. Rhodamine B has been used as model compound and all experiments were carried out at normal atmospheric pressure and temperature (25+/-1 degrees C) under open-wide system. The different pH values from 7.0 to 14.0 and the catalyst recycling were investigated. The results indicated that ethylenediamine-CuCl(2) was an effective catalyst in the degradation of Rhodamine B at pH 7.0-12.0. It would provide a useful insight into the development of new routes in organic wastewater treatment.
