METHOD FOR SEPARATING IRON ELEMENT FROM BRINE AND USE THEREOF

Provided is a method for separating iron element from a brine, comprising: adding a pH regulator to the brine to adjust the pH value of the brine to 6.0-7.0, and controlling the temperature of the brine at 75-90 °C; introducing an oxygen-containing gas into the brine to enable the iron element in th...

Zusammenfassung:	Provided is a method for separating iron element from a brine, comprising: adding a pH regulator to the brine to adjust the pH value of the brine to 6.0-7.0, and controlling the temperature of the brine at 75-90 °C; introducing an oxygen-containing gas into the brine to enable the iron element in the brine to form magnetic iron(III) oxide; and separating the magnetic iron(III) oxide from the brine by means of magnetic adsorption to acquire an iron-free brine. The brine comprises a geothermal brine.
