However, little is known about the uptake mechanism or speciation of uranium in gypsum. In this study, synthesis experiments suggest an apparent pH control on the uptake of uranium in gypsum at ambient conditions: increase in U from 16 μg/g at pH = 6.5 to 339 μg/g at pH = 9.5. Uranium L 3-edge synchrotron X-ray absorption spectroscopic ...

Gypsum and anhydrite are the neutral salts of a strong acid and strong base and do not increase or decrease acidity. Dissolving gypsum and anhydrite in water or soil results in the following reaction: (CaSO 4 ·2H 2 O) = Ca 2+ + SO 4 2-+ 2H 2 O. They add calcium ions (Ca 2+) and sulfate ions (SO 4 2-), but do not add or take away hydrogen ions ...
