Effect of heavy metals impurities upon nucleation kinetics of NaCl [Nacl' ün çeki?rdeklenme ki?neti??i?ne a?ir metal safsizliklarinin etki?si?]

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