Conducting Iron Hydroxide Precipitation Reactions at High Temperature and High Pressure
Iron hydroxide precipitation is an important process in many subsurface environments, such as managed aquifer recharge, geologic carbon sequestration, as well as water injection enhanced oil production. Since iron hydroxide is the sink of many aqueous pollutants including: heavy metals, arsenic, and organic pollutants, it is important to study iron hydroxide precipitation rates, as well as the permeability decrease in an aquifer caused by its precipitation. It’s also important to study the mobilization of aqueous pollutants.
In this application note the following experiment was conducted with acidic pH, which may corrode the inside wall of the syringe pump. To prevent the iron hydroxide precipitation inside the syringe pump, a novel setup was designed using the syringe pump and a Parr reactor.
