Abstract
Biomineralization involves the interaction between biological and mineralogical processes which encompasses both the crystallization and dissolution of minerals. Efforts have been undertaken to investigate the crystallization process under microgravity conditions, but the current understanding of dissolution in microgravity is limited, and no experiments have been designed to specifically investigate this topic. This study aimed to design dissolution experiments for pyromorphite as a model apatite using the Random Positioning Machine (RPM) for microgravity simulations. As a control, a gyratory shaker was used to agitate the mineral during dissolution. The changes of Pb and P concentrations over time in dissolving 0.05 KNO3 solution with pH = 2.0 was measured using the ICP‒MS technique. Pyromorphite dissolved congruently achieving equilibrium with the solution within 3 days. The solubility of the mineral in terms of Pb and P concentrations was higher in RPM experiments, however, estimated solubility constants for both experiments (Ksp) were not significantly different (p = 0.124, Student's t-test). It has been concluded that the proposed experiment can serve as a methodology to further investigate the solubility of apatites in microgravity conditions. However, it is challenging due to low solubility and analytical methods limitation.
