Transformation of schoepite into the uranyl oxide hydrates: Becquerelite, billietite and wölsendorfite

Solubility measurements of the uranyl oxide hydrate phases metaschoepite, compreignacite, Na–compreignacite, becquerelite, and clarkeite

“…There have also been numerous measurements of the solubility of synthetic becquerelite, producing lg K sp values from (41.89) to (43.70) [32][33][34]; however, none of these studies constrained K sp values by conducting experiments that started from supersaturated conditions. Casas et al [35] measured the solubility of becquerelite using a natural sample and calculated a lg K sp value of (29).…”

Review of uranyl mineral solubility measurements

“…Vochten et al [39] also measured the solubility of becquerelite from undersaturation with respect to U. The authors characterized the mineral phase prior to the solubility experiments using a range of analytical approaches including bulk phase analysis by atomic absorption spectroscopy (AAS), XRD, and TGA.…”

Experimental determination of UO2(cr) dissolution kinetics: Effects of solution saturation state and pH

“…The log 10 equilibrium constants (K) for all minerals and aqueous species are based on either measured or estimated free energy values from various literature sources [52][53][54][55][56][57][58][59][60][61][62][63].…”
