Abstract
In a method for extracting boron from a boron solution, a boron solution is processed at an electrocoagulation system utilizing metal electrodes to generate a sludge comprising water, metal oxide and boric oxide, wherein the boric oxide is encapsulated within the metal oxide. The sludge is filtered at a dewatering system to remove at least a portion of the water from the sludge to generate a cake. The cake is processed at a furnace to generate metal oxide borate.

A method for generating metal oxide borate from a boron solution, the method comprising:
- processing a boron solution at an electrocoagulation system utilizing metal electrodes to generate a sludge comprising water, metal oxide and boric oxide, wherein the boric oxide is encapsulated within the metal oxide;
- filtering the sludge at a dewatering system to remove at least a portion of the water from the sludge to generate a cake;
- and
- processing the cake at a furnace to generate metal oxide borate.
A method for generating metal oxide borate nanorods from a boron solution, the method comprising:
- processing a boron solution at an electrocoagulation system utilizing sacrificial metal electrodes to generate a sludge comprising water, metal oxide and boric oxide, wherein the boric oxide is encapsulated within the metal oxide;
- wherein the processing the boron solution at the electrocoagulation system comprises:
- generating metal hydroxide and boric acid from the boron solution;
- and
- generating the water, the metal oxide and the boric oxide from the metal hydroxide and the boric acid;
- filtering the sludge at a dewatering system to remove at least a portion of the water from the sludge to generate a cake;
- and
- processing the cake at a furnace to generate metal oxide borate, wherein the processing the cake at a furnace to generate the metal oxide borate comprises:
- heating the cake to at least 100 degrees Centigrade to remove additional water from the cake;
- and
- heating the cake to 600 to 1400 degrees Centigrade to morphologically transform the cake into metal oxide borate nanorods.
