Boric acid and sulfuric acid were added to deionized water at initial concentrations of 0.7 g L −1 of boron and 50 g L −1 of sulfuric acid. The experiments were carried out in a 2.5‐L baffled vessel (diameter 150 mm, height 150 mm), mechanically stirred by a Rushton turbine (diameter 50 mm) and kept at constant temperature by a double‐wall–jacketed vessel.
