Key Points

The improved model allows for more accurate predictions of Tc(iv) solubility in saline environments, aiding waste management.
Key findings show that solubility changes significantly across different ion concentrations and types, influencing nuclear waste strategies.
The analysis employs the extended Pitzer activity model, ensuring precise calculations for nuclear waste disposal scenarios.
This model adoption could improve safety measures in nuclear waste management, necessitating further research in broader contexts.

Implication

Improved Pitzer model estimates solubility and hydrolysis of Tc(iv) in multiple salt systems, indicating relevance for nuclear waste disposal.

Abstract

The study provides an extended and improved Pitzer model for Tc( iv ) in NaCl, KCl, CaCl 2 and MgCl 2 systems, which can be implemented in geochemical calculations of relevance in the context of nuclear waste disposal.
