Chapter 11 - Surface Complexation of Zinc Cation with Hydroxyapatite, Molecular Dynamics and Surface Durability

摘要: This chapter presents a discussion on surface complexation of zinc cation with hydroxyapatite, molecular dynamics, and durability. The contributes to the establishment consistent database sorption thermodynamics dissolution kinetics for solution-mineral interactions in apatite-H 2 O-Zn 2+ system. reviews existing potentiometric titration data models concerning apatite. Experimental results are presented from stirred flow-through reactors study adsorption Zn at apatite isolate this mechanism competing reactions—for example, or precipitation. Through dynamics computations, level, reaction steps preceding per se discussed. effect hydroxyapatite is determined discussed chapter. Archaeometrical studies that show long-term foreign metal ions, such as bones teeth apatite-rich compound remains. proton charge mineral typically measured by titrations zetametry. model describes apatite, assuming two amphoteric hydroxyl sites—namely, calcium sites, ≡CaOH, phosphate ≡POH. Cations present solution Mn form complexes reactive groups. At microscopic proceeds steps, formation an outersphere complex then within picoseconds innersphere complex.
