Kinetics of isotopic exchange between calcium molybdate and molybdate ions in aqueous solution

The heterogeneous isotopic anion exchange kinetics and equilibria between calcium molybdate and sodium molybdate solutions have been studied by using ⁹⁹Mo as tracer in batch experiments...

Characterization of thin water layers in pulp by tritium exchange. Part 1: Methods development

A new technique for measuring the monolayer water content of fiber is presented. Tritiated water is added to a pulp/water suspension, whereupon the tritium partitions between the bulk water and the pulp...
