Two anti-dissolution mechanisms of aragonite in acidified artificial seawater were investigated by monitoring the dissolution process in the presence of organic and inorganic additives. Among them, the carboxyl functional group (RCOO−) in PAA bonds with Ca2+ and bicarbonate, while strong protonation of silicates directly binds to hydrogen ions from bicarbonate. These interactions ultimately form stable polymer-rich amorphous calcium carbonate and dense silica layers on the surface of aragonite, effectively inhibiting further dissolution under dissolved CO2.
