Estudo do equilíbrio de fase sólido-líquido para o sistema de mistura ternário KCl, MnCl2.4H2O e H2O

Abstract

Batteries have become essential over the years, especially with the technological revolution and the increasingly common use of smartphones, notebooks and tablets. However, the increasingly common use of these products has triggered an environmental problem due to the disposal of these products as soon as their useful life ends. Those batteries have in their components Zinc or Manganese, heavy metals and that in contact with the soil or water are extremely toxic to living beings. The general objective of this research is to study the solid-liquid phase balance for the ternary mixing system formed by potassium chloride (KCl), manganese chloride tetrahydrate (MnCl2.4H2O) and water (H2O) at 25° C and 1 atm atmospheric pressure using the quasi-isothermal thermometry technique. Thus, discovering possible ways to recover these metals and mitigate the harmful effects of these metals on the environment.
