METHOD FOR SEPARATING IRON ELEMENT FROM BRINE AND USE THEREOF

The present disclosure provides a method for separating iron element in brine. A pH adjusting agent is added to brine, to adjust the brine to pH between 6.0 and 7.0, and the temperature of the brine is controlled to between 75°C and 90°C. An oxygen-containing gas is introduced into the brine, to cov...

Zusammenfassung:	The present disclosure provides a method for separating iron element in brine. A pH adjusting agent is added to brine, to adjust the brine to pH between 6.0 and 7.0, and the temperature of the brine is controlled to between 75°C and 90°C. An oxygen-containing gas is introduced into the brine, to covert the iron element in the brine into magnetic iron oxide. The magnetic iron oxide is separated from the brine by magnetic adsorption, to obtain an iron-removed brine. The brine includes geothermal brine.
