| Abstract: | This paper introduces the working principle of magnetic field liquid bed containing zinc particles.The best technological conditions are determined through experiments to recover chromium and nickel directly from the electroplating spent solution. The research indicates that the reclamation of Cr and Ni are respectively 97.5% and 98.2% with the purity over 97% after the liquid bed runs 2 h.The present method provides an economical and practical way to recover heavy metal ions from chemical spent solutions. |
