Using magnesium hydroxide for ocean alkalinity enhancement: elucidating the role of formation conditions on material properties and dissolution kinetics

Mg(OH)2 holds potential as an alkalinity source for Ocean Alkalinity Enhancement (OAE). In this study, Mg(OH)2 was produced via precipitation from the alkalinity exchange of NaOH addition into brine. Mineralogy characterization (XRD, EDS, SEM) and dissolution kinetics (total alkalinity release rates...
