    ui.adsabs.harvard.edu/abs/2016EGUGA..18.8312G/abstract Seven samples of hydroxyl analogues of pyromorphite-mimetite solid solutions series were synthesized from aqueous solutions at 80° C in a computer-controlled chemistate: 200 mL aqueous solutions of 0.05M Pb(NO3)2 and 0.03M KH2AsO4 and/or KH2PO4 were dosed with a 0.25 mL/min rate to a glass beaker, which initially contained 100 mL of distilled water. Constant pH of 8 was maintained using 2M ...

    ui.adsabs.harvard.edu/abs/2012EGUGA..14.9546K/abstract The results show that the new phase was only hydroxylpyromorphite even in the presence of Cl. Observations of broken crystals show partial replacement of cerussite by polycrystalline hydroxylpyromorphite, preventing even fine scale surface micromorphology.

    www.sciencedirect.com/science/article/pii/S0277538715003575 The synthesized hydroxylpyromorphite–hydroxylmimetite solid solution series were characterized by FTIR. The effect of substitution of [PO 4] 3− by [AsO 4] 3− on changes in lattice parameters and spectral properties has been explained based on correlation between chemical composition and the peak positions. The As/As + P ratios can be used for composition determination.

  • CX7-X3K - Hydroxylpyromorphite, Quartz

    www.mindat.org/CX7-X3K Hydroxylpyromorphite is a key phase used for remediation of Pb-polluted aquifers and its ability to remove Pb from drinking water has been extensively studied. The crystal structure provides a better understanding of the possible anion column arrangements in pyromorphites and other Pb-bearing apatite group minerals, which may help guide and ...
