title: [Effect of nucleation modes on the induced crystallization process for copper contained wastewater treatment].
abstract: The effect of nucleation modes on the induced crystallization process for copper contained wastewater treatment was studied. Tests were undertaken to observe the difference of copper removal efficiency and the crystal growth with homogeneous and heterogeneous nucleation. When the influent copper concentration was 50 mg x L(-1), copper removal efficiency could achieve 98.0% with the heterogeneous and 26.3% with homogeneous nucleation. And the SEM-EDS showed that the growth of crystals with heterogeneous nucleation was better and the purity of the crystals was higher than that with homogeneous nucleation. It is obvious that the homogeneous nucleation was an unfavorable condition on the induced crystallization process. Then the research devoted to discuss the process of induced crystallization with the two different nucleation mode and analysis the influencing mechanism of the homogeneous nucleation on the induced crystallization.
