Implication

Study applies a novel model for calculating ionic activity in heavy metal salt solutions, highlighting ionic associations and implications for environmental systems.

Key Points

The study reveals that including ionic association can significantly reduce calculation deviations in ionic activity coefficients.
Mean ionic activity coefficients for cadmium and zinc salts achieved deviations below 2% and 5.5%, respectively, enhancing model reliability.
Calculations extend the applicable molality range for nickel and cobalt salts up to 5.0 mol/kg and 5.5 mol/kg water.
The cubic-plus-association equation of state offers new insights into ion-specific effects in environmental and industrial applications.
