“…[8,9,[11][12][13][14][15] Generally, these studies have indicated the formation of inner-sphere T-shaped solution phase geometry. [19] This study has been extended to understand the interaction between Np V O 2 + and Th IV cations under varying experimental conditions such as nitric acid (1-6 m HNO 3 ), Th IV (up to 0.86 m) concentrations, and temperature (20-70°C). [15] Experimental conditions such as ionic strength, metal concentrations, nature of acid and its concentration, and temperature show significant influence on cation-cation interactions (CCIs) in aqueous media.…”
