Cu(II) and Ni (II) are heavy cations commonly found in electroplating waste. These cations are generally not easy to separate because their diameter is nearly the same. <br /> <br /> <br /> <br /> <br /> This cause the modification of a material for the separation of these cations is not easy. In this experiment, the two kinds material separating of alumina-bentonite composite and nepheline used to separate a mixture of Cu(II) and Ni(II). In this study, it was found that nepheline is a better separating media for Ni (II) from binary mixture of Cu(II) and Ni(II) than alumina-bentonite composite. As comparison, the separation of a mixture of Cu(II) and Pb(II) was conducted. It was found that Pb(II) could be separated from the mixture using nepheline as well.
