The sulfate mineral jarosite (KFe3(SO4)2(OH)6), its chromate analog (KFe3(CrO4)2(OH)6), and seven precipitates with intermediate compositions (KFe3(CrXS(1-X)O4)2(OH)6) were synthesized. The unit cell volume of the precipitates ...
The solubility of ettringite (Ca6[Al(OH)6]2(SO4)3 . 26H2O) was measured in a series of dissolution and precipitation experiments at 5-75°C and at pH between 10.5 and 13.0 using synthesized material. Equilibrium was established ...
The solubility of KFe(CrO4)2·2H2O, a precipitate recently identified in a Cr(VI)-contaminated soil, was studied in dissolution and precipitation experiments. Ten dissolution experiments were conducted at 4–75°C and initial ...
