Özet
In this study, effects of heavy metal's impurities (Pb2+, Fe3+) on nucleation kinetics of NaCl in crystallization medium were investigated. The tests were conducted by taking into account industrial production conditions of the salt (NaCl) and taking measurements of the setting period of the solution. In the study, where the tests were carried out in both pure medium and in the presence of impurities, it was observed that the stirring process increases the nucleation rate of NaCl. It was found that heavy metal impurities significantly reduce the nucleation rate and that this effect becomes more vivid with lead ions impurities (Pb2+). The study also found that the presence of seed crystal increases the nucleation rate. However; it was also clear that the negative effects imposed by the heavy metal impurities on nucleation still kept persisting.
