This work investigated the effective precipitation recovery of boron by chemical oxo-precipitation (COP), which uses hydrogen peroxide (H2O2) to transform aqueous boron to easy-precipitating perborates at room temperature. By using barium hydroxide (Ba(OH)2) as a precipitant, the boron removal enhanced with treatment time and the boron level was eventually reduced from 1000ppm to 3ppm in four hours...
